“…To achieve the spatial resolution, time resolution and rate requirements of the upgrade, a full readout chain has also been developed alongside the detector [6]. The on-detector electronics are developed by the INFN section of Turin and revolve around a new Application Specific Integrated Circuit (ASIC), specifically designed for the readout of GEM detectors, called TIGER (Torino Integrated GEM Electronics for Readout) [7]. This new chip is capable of performing simultaneous charge and time measurements on input signals up to 50 fC for input capacitances up to 100 pF.…”

A ten years extension of the data taking of BESIII experiment, recently approved, motivated an upgrade program both for the leptonic collider BEPCII and for some of the sub-detectors of the spectrometer. In particular, the current inner drift chamber is suffering from aging and the proposal is to replace it with a detector based on cylindrical GEM technology. The CGEM detector is made of three coaxial layers of triple GEM. The tracker is expected to restore the efficiency, to improve the z determination and the secondary vertex position reconstruction with respect to the current inner tracker, with a resolution of 130 µm in xy plane and better than 350 µm along the beam direction. A cosmic telescope instrumented with two out of three layers is in operation in Beijing since January 2020, remotely controlled by Italian groups due to the pandemic situation. In this presentation, the general status of the project will be presented with a particular focus on the preliminary results from the cosmic data taking and future plans.

“…For such reason, the whole readout chain was designed keeping in mind strong adaptability and modularity. 3 Front-end electronics: TIGER ASIC TIGER (Torino Integrated GEM Electronics for Readout) is the ASIC designed for the readout of the CGEM-IT strips [11]. Each mixed-signal chip can handle the complete readout of the data incoming from 64 channels, providing time and charge measurement in order to satisfy all the design requirements (table 3) .…”

An innovative Cylindrical Gas Electron Multiplier (CGEM) detector is under construction for the upgrade of the inner tracker of the BESIII experiment. A novel system has been worked out for the readout of the CGEM detector, including a new ASIC, dubbed TIGER -Torino Integrated GEM Electronics for Readout, designed for the amplification and digitization of the CGEM output signals. The data output by TIGER are collected and processed by a first FPGA-based module, GEM Read Out Card, in charge of configuration and control of the front-end ASICs. A second FPGA-based module, named GEM Data Concentrator, builds the trigger selected event packets containing the data and stores them via the main BESIII data acquisition system. The design of the electronics chain, including the power and signal distribution, will be presented together with its performance.

“…A signal of about 100 fC per m.i.p. is collected on the strips and the TIGER (Torino Integrated Gem Electronics for Readout) electronics [6] is used to measure the time and the collected charge. Two ASICs are installed on a Front-End Board (FEB) to read the signal from 128 strips.…”

BESIII is a multipurpose spectrometer optimized for physics in the tau-charm energy region. Both the detector and the accelerator are undergoing an upgrade program, that will allow BESIII to run for 5 to 10 more years. A major upgrade is the replacement of the inner drift chamber with a new detector based on Cylindrical Gas Electron Multipliers to improve both the secondary vertex reconstruction and the radiation tolerance. The CGEM-IT will be composed of three coaxial layers of cylindrical triple GEMs, operating in an Ar + iC4H10 (90:10) gas mixture with field and gain optimized to minimize the spatial resolution. The new detector is readout with innovative TIGER electronics produced in 110 nm CMOS technology. The front-end is a custom designed 64 channel ASIC featuring a fully digital output and operated in trigger-less mode. It can provide analog charge and time measurements with a TDC time resolution better than 100 ps, which will allow operating in μTPC mode. With planar prototypes, we measured an unprecedented spatial resolution below 150 μm in a 1 Tesla magnetic field in a wide range of incident angles of the incoming particle. Before the installation inside BESIII, foreseen in 2021, a long standalone data taking is ongoing at the Institute of High Energy Physics in Beijing; currently, the first two cylindrical chambers are available for the test, and are used to complete the integration between the detector and the electronics and to assess the required performance. In this proceeding, a description of the CGEM-IT project, the TIGER features and performance, and the results of the analysis of first cosmic ray data taking will be presented. Focus will be given on the strip analysis, from which it is possible to measure the basic properties of the detector, and the cluster analysis, where a comparison with the results with planar prototypes will be discussed. The first preliminary results on efficiency and spatial resolution will be also presented.
