The description of equipment and methods used for conducting ionizing radiation Accelerated Life Testing (ALT) of programmable hardware, especially Field Programmable Gate Arrays (FPGA) at the cyclotron is introduced. Methodology of testing and Single Event Effects (SEE) detection and online monitoring is described together with some results of testing several SRAM and Flash based FPGAs. In the course...
A multi-gap ionization monitor chamber has been developed by INFN and Torino University, for monitoring of high intensity pulsed charged particle beams. The read-out of the chamber is based on a 64-channel ASIC, designed in CMOS 0.35µm technology which features for each channel an independent current-to-frequency converter followed by a synchronous counter. The chip was designed for connecting each...
An innovative design of 16-channel front-end electronics for ionization chamber in monitoring proton beam profile has been developed to feature simplicity, low cost, durability, and reliability without compromising its performances. All the parts are available off the shelf. The front-end electronics board is powered by USB connection, through which the data are transferred to the host computer for...
The beam diagnostic system of the ATLAS detector comprises two diamond sensor based devices. The innovative Beam Conditions Monitor (BCM) is aimed at resolving background from collision particles by sub-ns time-of-flight measurement. The Beam Loss Monitor (BLM) is a clone of the LHC machine BLM system, replacing ionization chambers with diamond sensors. BCM uses 16 1 × 1 cm2 0.5 mm thick polycrystalline...
Collision rate monitors are essential in bringing particle beams into collision and optimizing the performances of a collider. In the case of LHC the relative luminosity will be monitored by measuring the flux of small angle neutral particles produced in the collisions. Due to the very different luminosity levels at the four interaction regions (IR) of LHC two different types of monitors have been...
