Oral Communication

This contribution reports on the results of large-area (2 cm$^2$) small pitch (55 μm) inverse Low-Gain Avalanche Detectors (iLGAD), bonded to Timepix3 readout chips. The ilGAD sensors were produced by Micron Semiconductor Ltd with the goal to obtain good gain uniformity and minimise the fill-factor issue present with traditional small-pitch LGAD designs. We have conducted detailed performance...

Oral Communication

The Low Gain Avalanche Diodes (LGADs) are silicon detectors that use the impact ionization process to achieve gain values of about $\mathcal{O}$(10). One of the important factors to consider when using LGADs for experiments studying charged cosmic rays in space is their timing performance. While conventional silicon microstrip sensors only provide spatial information of the charged particles...

173. Timepix4 Characterization with Monochromatic X-Ray Synchrotron Beam

Mr Alessandro Feruglio (INFN)

02/07/2024, 17:20

Oral Communication

Timepix4 is an application-specific integrated circuit (ASIC) developed by the Medipix4 collaboration [1]. Timepix hybrid detection systems are realized by bump-bonding the ASIC to pixelated sensors (pixel pitch 55 $\mu m$) of various materials and thicknesses to adapt the detection performances to different applications.
Timepix4 Time of Arrival (ToT) - Time over Threshold (ToT) data-driven...

167. First productions of large area Silicon Drift Detectors for the eXTP Wide Field Monitor instrument: test results and yield assessment.

Oral Communication

The enhanced X-ray Timing and Polarimetry mission (eXTP website, https://www.isdc.unige.ch/extp/) is a scientific space program that will look at X-rays coming from targets such as neutron stars, magnetars and black holes [1, 2] to study the state of matter under extreme conditions of density, gravity and magnetism. The eXTP satellite will be equipped with state-of-the-art instruments enabling...

104. First in vivo validation of a DROP-IN β-probe for robotic Radioguided Surgery in prostate cancer

Oral Communication

Radio Guided Surgery (RGS) is a nuclear medicine technique that directs surgeons towards tissue targets preoperatively defined on imaging-roadmaps such as PET/CT.
To this aim a radiopharmaceutical is injected into the patient before surgery, and the surgeon is given an intraoperative detector enabling the real-time identification of areas with accumulated radiotracer.
Typically utilizing...

138. Ion-beam therapy quality monitoring using secondary-ion tracking with Timepix3: first results of the InViMo clinical trial

Dr Laurent Kelleter (German Cancer Research Center DKFZ)

03/07/2024, 11:20

Oral Communication

Ion-beam radiotherapy uses steep dose gradients which makes it a highly effective cancer treatment but also susceptible to anatomical variations and patient setup shifts between treatment fractions. In-vivo monitoring with secondary radiation promises to reveal information about the daily treatment quality. The InViMo clinical trial at the Heidelberg Ion-Beam Therapy Center (HIT) aims to...

156. Recent developments in radiological scene data fusion

Jayson Vavrek (Lawrence Berkeley National Laboratory)

03/07/2024, 11:40

Oral Communication

Understanding the distribution, isotopic composition, and activity of a radiological threat object or contamination area is crucial for responding to both short- and long-term nuclear threats. To address these needs, radiological Scene Data Fusion (SDF) has been developed at Lawrence Berkeley National Laboratory (LBNL) and the University of California, Berkeley (UCB) over the past decade to...

222. 100µPET: an ultra-high-resolution silicon-pixel-based PET scanner

Mateus Vicente Barreto Pinto (Universite de Geneve (CH))

03/07/2024, 12:00

Oral Communication

The 100µPET project is developing a pre-clinical medical scanner for positron-emission tomography (PET) with ultra-high-resolution molecular imaging capabilities. The scanner is composed of multiple layers of monolithic active pixel sensors (MAPS) connected to flexible printed circuits (FPC). With pixels of 150 µm pitch and a thickness of 280 µm + 300 µm (MAPS + FPC), the scanner achieves...
