PETsys TOF ASIC evaluation kit

PETsys Time-of-Flight ASIC evaluation kit


Figure 1: The FEM128 module has two ASICs, and has connectors accepting a Hamamatsu S13361-3050Ax-08 MPPC 8x8 array, or a KETEK PA3325-WB-0808 array. 

The PETsys TOF ASIC evaluation kit (Fig. 2) is a complete readout kit allowing to read up to 128 SiPM channels. It can be used in applications where only a small number of channels needs to be read, and it provides an easy to use, and low cost, way for exploring the unique, powerful and verstile features of the PETsys TOFPET2 ASIC.
The e-kit comes with a FEB/D board with Ethernet link, and two TOFPET2 ASIC test boards (Fig. 1). Each test board has one ASIC reading 64 channels. The test boards have connectors that directly accept the Hamamatsu S13361-350Ax-08 8x8 MPPC array, or the KETEK  PA3325-WB-0808 array. With some small adapter boards, these
test boards will equally well read analog SiPMs from other vendors.
Flexible cables connect the TOFPET2 ASIC test boards to the FEB/D board, providing great flexibility in the experiment setting.
We provide all the firmware and software needed for acquiring and analysing the signals of the ASICs, thus enabling the simultaneous reading of up to 1024 pixels. The source code of the DAQ software in the DAQ PC is provided, giving the user all freedom for exploring the performance of the system, or for adapting it to his particular needs.

Figure 2: The PETsys TOF ASIC evaluation kit consists of a FEB/D board (bottom) with Ethernet link to the computer, and a mechanical assembly (top) with two TOFPET2 ASIC test boards, two KETEK SiPM pixels, two LYSO crystals and a holder for placing a 22Na source in between.

 For an easy start we supply the e-kit with two KETEK SiPM pixels mounted on a board that plugs in the connector on the TOFPET2 ASIC test board, two LYSO crystals of 3x3x5 mm2, and a holder for placing a standard circular 22Na source in between. We also provide a cooling box with a Peltier element allowing stable and reproducible measurements. The box also protects the measurement setup from ambient light.
Included in the price of the e-kit we provide a hands-on and individual training for one or two people. The training introduces the user to the use of the e-kit, the readout electronics and the software.
