WEBVTT 00:00:00.000 --> 00:00:03.000 The recording has stopped. So, hello, can you see my screen share? This meeting is being recorded. 00:00:03.000 --> 00:00:09.000 Could you see my screen shared? 00:00:09.000 --> 00:00:26.000 Yes. Okay. Okay, so thank you for the kind invitation and I am pleased to give this talk cpc towards a sustainable green higs factory. 00:00:26.000 --> 00:00:36.000 So CPC. As you know, is only one of the future history his factory plans. 00:00:36.000 --> 00:00:48.000 So this is a circular one. So in addition to linear ones So this is a CPC looks like 100 kilometer So, um. 00:00:48.000 --> 00:00:59.000 For the Higgs energy and other through energies wz and tt bar as So this is the scientific goals. 00:00:59.000 --> 00:01:16.000 So to simplify the scientific goal, we can see that taking only Higgs, for example, for 10 years running For the baseline, we will collect three millions of heaps. 00:01:16.000 --> 00:01:26.000 For example, so this is the goal So to reach this goal, we need to optimize the machine in terms of cost. 00:01:26.000 --> 00:01:56.000 And the surely which connects in relation with CO2 emissions. Secondly, we have to identify the technology with has a big impact or interrelation between the the power consumption and the technology And then I make R&Ds and technology improvements. 00:01:56.000 --> 00:02:01.000 And also, we needed to recover the use, the waste, the heat. 00:02:01.000 --> 00:02:12.000 And also use grain energy. So this is some aspect. And there are some efforts And the papers published, I listed here. 00:02:12.000 --> 00:02:20.000 So this is the CPC machine. And this is the budget. 00:02:20.000 --> 00:02:40.000 For the energy repetition, for example, for the first block this is the Higgs running of baseline so you can see that the total power is about 260 megawatt. 00:02:40.000 --> 00:02:52.000 And inside these total power budgets. The most power consumption is from RF. 00:02:52.000 --> 00:03:14.000 And then from the magnets and the utilities which uh to There are many cooling waters and something uh there's a low temperature heat there and also cryogenic system. So I just give you so several examples of this source of energy consumption. 00:03:14.000 --> 00:03:26.000 Okay, so this is the In terms of machine optimization design so The first part is how long is the machine? 00:03:26.000 --> 00:03:46.000 And… And how to design this machine to make the including the operation to reach the design goal, that means how many hicks you want and to make a cost a minimum because if a minimum design is different. 00:03:46.000 --> 00:03:51.000 The lens of the machine is different. Surely, the cost will be different. 00:03:51.000 --> 00:04:17.000 And also the CO2. To compare the heat as a Higgs factory imagine we if you compare the Higgs per the co2 Per hex, that means during all your scientific operation to get these several millions of Hicks and the co2 00:04:17.000 --> 00:04:36.000 And then you want to make it a minimum. So this is uh But surely to calculate that, you need to make some assumptions. For example, to compare with different machines and we assume we are all using green energies. 00:04:36.000 --> 00:04:43.000 But in reality, surely different places might use different kinds of energies. I will show you. 00:04:43.000 --> 00:05:08.000 So this is the electricity status in China, for example. And you can see different places, province and the composition of the type of energies there. So I will not distress like information And also, this is the carbon intensity expectation from 20 00:05:08.000 --> 00:05:16.000 From here from 2010. Until 2035. This is just for you uh information late. 00:05:16.000 --> 00:05:36.000 But China now is this since April, this year april Already nuclear power is already Both including the built and the planned under construction already reached the first in the world. 00:05:36.000 --> 00:05:47.000 And in terms of 2035, So the nuclear power in China will be 10% of the total electric power. 00:05:47.000 --> 00:06:01.000 So the… the carbon, the CO2 emission Around 30 will be achieved the peak And at 60, we'll get neutrality. 00:06:01.000 --> 00:06:23.000 Before 60 2060 and from this power breakdown. So we identified some key technologies really to to try to reduce the the power of the machine. 00:06:23.000 --> 00:06:37.000 And to um to recover some waste heat energy as energy So this is something as a goal. So we know what we should do. 00:06:37.000 --> 00:07:00.000 And in the following is what we have done. So the key thing, as I said, the RF is the most powerful consumed and surely the cholesterol is the key thing. So if you increase 1% even, so you will reduce the power. So this is a very significant 00:07:00.000 --> 00:07:25.000 Impact. So we have developed the high efficiency clerstones And I will not go to the detail. And we have reached 78 This is the highest in the world. And we try to use energy recovery type cholesterol to single stage can reach 85 and two stage 00:07:25.000 --> 00:07:32.000 In theory can reach 90%. So this is something we are working on. 00:07:32.000 --> 00:07:37.000 Okay, for example, this is an energy recovery colostrone. It looks like that. 00:07:37.000 --> 00:07:46.000 This is one stage one. 85%. If two-stage collector and then it can reach 90%. 00:07:46.000 --> 00:08:13.000 So about superconducting accelerator, which consumes also for cryogenics so if the Q factor can be increased. So also the cryogenic system, AC power will reduce so this is the figure to show if you increase the Q factor and then you will reduce cryogenic AC power. 00:08:13.000 --> 00:08:31.000 So this is the cavity and the Q factor. For example, this is 651 cell. This is the highest in the world the Q value six 10 to 10. 00:08:31.000 --> 00:08:51.000 Now, also other advanced technology advanced about an album 13 in this case, if this technology has a breakthrough And the cryogenic system can work at two 4.2K instead of 2k in this case the cryogenic power can be reduced. 00:08:51.000 --> 00:09:07.000 So this is something we're working on that. And also, as I said, the magnet is a big part of the power consumption source. And then there are some development for the permanent magnets. For example, this is dipoles. 00:09:07.000 --> 00:09:26.000 Has been used in HAPS light source and uh this we have experiences in these permanent magnets and also uh we are trying to, we're developing permanent magnates of other quadrupals, which can be adjusted. 00:09:26.000 --> 00:09:35.000 Not a fixed value, but can adjust. So this is something underway. 00:09:35.000 --> 00:09:42.000 Also the power supply and solid state And also. 00:09:42.000 --> 00:09:56.000 The heat pump, this kind of thing to try to recovery the the ambient, the heat ways to heat uh to use it. 00:09:56.000 --> 00:10:26.000 And also, sorry, and also by using the these heat recovery chillers unit and We have… than that in helps light source to try to recover the heat of 42 degree water heat so this is It's a low, low temperature heat, very difficult to recover. Anyway, these kind of things 00:10:33.000 --> 00:10:42.000 Is in our field of research and also gain some experiences an existing machine like HAPS. 00:10:42.000 --> 00:11:08.000 And also, we try to use solar Energy, photonic energy for example HAPS is a machine of 30 megawatt and 10 megawatts now we can produce by itself on the roof of the machine And 10 megawatts has been produced not yet into the network 00:11:08.000 --> 00:11:14.000 But anyway, this is some something encouraging. 00:11:14.000 --> 00:11:21.000 Okay, so we also have efforts to make international collaborations on these subjects. 00:11:21.000 --> 00:11:28.000 And we had a mini workshop in hong kong uh two years ago. 00:11:28.000 --> 00:11:54.000 Last year, sorry, January. And mini workshop on green x-rator and the colliders. So you can find the names you're familiar And so we have… talks and works and in these fields in relation with the international efforts. Okay, so these cpc milestone 00:11:54.000 --> 00:12:16.000 So it's a big endeavor. For the human being of this kind of a big machine After the Higgs discovery at sun so we hope these international projects can offer to the high energy physics community an early Higgs factory. 00:12:16.000 --> 00:12:27.000 And hopefully these can be Stub construction 27 and completed the construction around 35. 00:12:27.000 --> 00:12:37.000 So this is a rough plan. Okay, I stop here. And so any questions? 00:12:37.000 --> 00:12:38.000 Thank you so much, J. Any questions? 00:12:38.000 --> 00:13:05.000 Thank you so much, Jean. Any questions? 00:13:05.000 --> 00:13:06.000 Sorry, in the chat. Sorry for the echo. 00:13:06.000 --> 00:13:10.000 Sorry, in the chat. Sorry for the echo. 00:13:10.000 --> 00:13:11.000 I was just wondering… When would you think you can implement or version of the ice cream? 00:13:11.000 --> 00:13:17.000 I was just wondering… We had to drink you can implement or version of the ice cream. 00:13:17.000 --> 00:13:24.000 Excuse me, the voice is there's an interruption. So would you please repeat your question? 00:13:24.000 --> 00:13:25.000 Yes, I think in one of the slides around number seven, right? 00:13:25.000 --> 00:13:29.000 Yes, I think in one of the slides around number seven, Rick. 00:13:29.000 --> 00:13:30.000 You were mentioning the flies. When do you think you invented? 00:13:30.000 --> 00:13:36.000 You were mentioning the replacement. And do you think it 00:13:36.000 --> 00:13:42.000 Pages. Page seven no which one? 00:13:42.000 --> 00:13:43.000 Let me just see. One of the next ones? 00:13:43.000 --> 00:13:49.000 Let me just see. One of the next ones? 00:13:49.000 --> 00:13:50.000 A bit more. They don't checking the slides as well. 00:13:50.000 --> 00:14:08.000 A bit more. They don't check any slides as well. 00:14:08.000 --> 00:14:09.000 I'm just checking in. Tell you the exact number. 00:14:09.000 --> 00:14:20.000 Which one? I'm checking… 00:14:20.000 --> 00:14:21.000 So inside number. 00:14:21.000 --> 00:14:26.000 So I remember… 00:14:26.000 --> 00:14:27.000 The one after the green. Oops. So 13. 00:14:27.000 --> 00:14:34.000 The one after the degree Sotarin. 00:14:34.000 --> 00:14:35.000 Number 13. Yes, sir. 00:14:35.000 --> 00:14:43.000 Sorry? Number 13. Ah, 13. Okay. Yes. Just a moment. There's no number seven. 00:14:43.000 --> 00:14:48.000 Eight. Nine. 10, 11. 00:14:48.000 --> 00:14:52.000 13 here. Right? 00:14:52.000 --> 00:14:53.000 Yes, thank you. I'm just wondering when you plan to implement the fourth question? 00:14:53.000 --> 00:14:59.000 Yes, thank you. I'm just wondering when to implement the fourth policy? 00:14:59.000 --> 00:15:00.000 Understood that currently you are at the server, right? 00:15:00.000 --> 00:15:07.000 Understood that currently you are at the server. So this chlystron is under study. 00:15:07.000 --> 00:15:23.000 And the principal proof has been made for the collector and then uh now we are doing that So this is the first stage is we build the clitstrom And it looks like that on the bottom. 00:15:23.000 --> 00:15:45.000 This cholesterol and the collector has been tested previously so so this is um the principle is here on this top picture and then top picture this is under maybe after say two years one in more than one year and this cholesterol can be 00:15:45.000 --> 00:15:49.000 Completed. Okay. 00:15:49.000 --> 00:15:54.000 Okay. 00:15:54.000 --> 00:15:55.000 Thank you so much for the talk. Okay, thank you. 00:15:55.000 --> 00:15:57.000 Thank you so much for the talk. 00:15:57.000 --> 00:16:01.000 Also completed.Also completed.
