Experimental overview 1h
(Source, Cooling, Transport, Launching, Interferometer, Detection)
+ Desired Parameters
-- Atom numbers
-- Temperatures (Horizontal/Vertical)
-- Repetition rate / Interleaving sequences?
+ Further considerations:
-- AION-100 requires O(20) sources and laser systems
-- Compatibility between systems vs exploring different options.
-- Shall all systems be the same?Speaker: Richard Hobson (National Physical Laboratory) -
Source + Pre-cooling 45m
(e.g. 2D MOT) Designs: Oxford, AOSense, NPL, MAGIS, Amsterdam, MPQ, LE

Second cooling + Transport 45m
Cooling Options:
+ Adiabatic decompression
+ Evaporative cooling
+ Delta-kick cooling
Transport Options:
+ Moving Dipole Trap (e.g. focus-tuneable lenses)
+ Conveyer Belt (moving lattice)
+ Free flight (launch and recapture via lattice, combined with delta-kick cooling)
Questions:
+ Required temperature
+ Possibility of laser cooling in main tube?
+ Desired repetition rate 1064nm laser best choice for transport?Speaker: Ulrich Schneider (University of Cambridge) -
Launch sequence 15m
- Laser, 1064nm ?
- Moving vs accelerated lattice?
-
- Potential for interleaving sequences?

Synergies with MAGIS 1h
General focus on transport, launching, laser — how much should/could AION use from MAGIS
Laser:
Are there plans using a far detuned laser (1050-1070nm) or a system close to the red MOT line
for transport and launching?Scaling to 100:
How to scale from 10m to 100mFuture level of cooperation for further development.
+ Do we effectively want to split further developments between MAGIS and AION,
or do we develop independently and periodically share the best developments? -
