LGAD technology for HADES, accelerator and medical applications

Development of a double-sided LGAD prototype from single-sided sensors: design, characterization, and proof of principle

“…HADES experiment utilizes a variety of beams, including pions, protons, and heavy ions, and employs multiple detector technologies for beam monitoring and reaction-time determination, such as diamond detectors [12][13][14] and LGAD sensors [4,7]. The LGAD sensors used in this project had an active area of 8.6 mm × 8.6 mm and featured strip segmentation on the gain side with a 100 μm pitch.…”

“…In many applications, however, the material budget is equally critical -for example in low-momentum particle tracking, medical imaging (e.g. ionCT) [5,6], or fixed-target experiments for reaction time determination [4,7] where detectors are placed directly in the primary beam. A promising approach to address these constraints is a double-sided strip configuration, well established in standard silicon detectors but not yet fully explored for LGADs.…”

LGAD technology for heavy ion detection and radiation damage diagnostics in diamond

“…Arranged perpendicularly to each other, the LGAD sensors enabled two-dimensional position reconstruction in a matrix configuration of 45 × 45, corresponding to 2025 effective pixels. Notably, LGAD sensors of this type in conjunction with the same amplifier design, are currently employed in a prototype ion CT system [5,6], were used for beam diagnostics [7] and utilized as a T 0 detector for a proton beam in the HADES experiment [8]. Analog signals from the detector, after amplification by the previously described amplifier system, are transmitted to the DiRich5s system [6].…”

First experimental time-of-flight-based proton radiography using low gain avalanche diodes

“…The TOF-iCT demonstrator utilizes an adapted version of the readout system for the LGAD-based HADES start-reaction time (T 0 ) detector developed at GSI (Krüger et al 2022). A brief description of all components of the TOF-iCT demonstrator, including the LGAD sensors, corresponding front-end electronics (FEE) and dataacquisition (DAQ) system, is given in the following.…”
