“…The cluster size is smaller for the y-strips because of the same readout quality issue discussed in the previous paragraph. These results are consistent with what has been observed with similar GEM detectors before [7].…”

a b s t r a c tWe report on the R&D effort in the design and construction of a large size Gas Electron Multiplier (GEM) for the Proton Polarimeter Back Tracker (BT) of the Super Bigbite Spectrometer (SBS) in Hall A at Thomas Jefferson National Laboratory (JLab). The SBS BT GEM trackers consist of two sets of five large GEM chambers of size 60 Â 200 cm 2 . The GEM chamber is a vertical stack of four GEM modules, each with an active area of 60 Â 50 cm 2 . We have built and tested several prototypes and the construction of GEM modules for SBS BT is ongoing. We describe in this paper the design and construction of the GEM module prototype as well as the preliminary results on performance from tests carried out in our detector lab and during test beam at Fermi National Laboratory (Fermilab).

“…Large-scale GEM detector requires a support of front-end electronics in a huge scale, especially in the spatial resolution demanding experiment [6]. In nowadays, most of the integrated pre-amplified data acquisition system is based on the FPGA (Field-Programmable Gate Array) technology for data processing and transmission [7,8]. When the detector detects the radiation, signals on every electrode will be amplified with integrated pre-amplifier, and transferred to the storage medium using FPGA based on a data bus such as CA-MAC or VME, regardless of whether the data is useful [7].…”

In this work, a serial on-line cluster reconstruction technique based on FPGA technology was developed to compress experiment data and reduce the dead time of data transmission and storage. At the same time, X-ray imaging experiment based on a two-dimensional positive sensitive triple GEM detector with an effective readout area of 10 cm × 10 cm was done to demonstrate this technique with FPGA development board. The result showed that the reconstruction technology was practicality and efficient. It provides a new idea for data compression of large spectrometers.

A: In this work, a fast method of vertex reconstructing for incident ions in GEM detectors was proposed. As inspired by the Time Projection Chamber (TPC), the time information of the consecutive signal samples from Front End Electronics (FEE) was employed. To demonstrate the method, an experiment involving a 2D-readout THGEM detector with an APV-25 FEE was taken. With one experiment dependent parameter in the analysis, the proposed method led to a spatial resolution of 0.45 mm, compared with the same number of 9.10 mm from the traditional center of gravity method.
