Description
A compact data acquisition and power supply system housed in a water cooled special
crate has been designed for the readout of the TOF (Time Of Flight) detector of the
Alice experiment at CERN. The Crate contains a 12 slot VME64X bus that houses 2400
multi-hit 25ps TDC channels (TRM), a Trigger Module (LTM), a Clock Distribution
Module (CPDM) and a data readout manger (DRM board) with two optical links and
Ethernet. The same crate hosts the branch controlled power supply modules for the
VME boards and the TOF detector front-end modules. The whole system shall be used
close to the TOF detector and will work under moderate magnetic field and radiation
(5 KGauss, 1.2 Gy/10 years TID). The TDC boards house TDC chips developed by
CERN/ECP-MIC Division (HPTDC). Due to the radioactive environment, an accurate
choice of components is required and the VME boards implement protections from
Single Event Latch-up and from Single Event Upset.
