14. ATLAS DAQ/HLT infrastructure

Dr Yuri ERMOLINE (MSU)

15/09/2005, 11:00

Oral

The ATLAS DAQ/HLT equipment is located in the underground counting room and in the surface building. The main active components are rack-mounted PC's and switches. The issues being resolved during the engineering design are powering and cooling of the DAQ/HLT equipment, monitoring of the environmental parameters, installation and maintenance procedures. This paper describes the ongoing...

42. The VMEbus processor hardware and software infrastructure in ATLAS

Mr Markus Joos (CERN)

15/09/2005, 11:25

Oral

Most of the off-detector custom electronics of the ATLAS data acquisition system such as the Read-Out Drivers or the Trigger and Timing Control system has been implemented in VMEbus. The paper describes the process of selecting a common VMEbus processor module for all VMEbus systems in ATLAS and the problems encountered during the evaluation of different candidate cards. Some...

21. A High Voltage System with 60 High Voltage Power Supply Channels in 2U Height EURO Crate

Masaya ISHINO ((International Center for Elementary Particle Physics (ICEPP), University of Tokyo))

Oral

A high voltage system includes 60 high voltage power supply channels in a 2U height EURO crate. The system is interfaced with a computer through USB interface. The output voltage of the channel ranges from 1 kV to 4 kV with an output current of more than 100 uA. Ripples on the output voltage is less than 100 mV in peak-to-peak amplitude. The output voltage can be set and monitored with...

52. Electromagnetic Compatibility of a DC Power Distribution System for the ATLAS Liquid Argon Calorimeter

Mr Georges Blanchot (CERN)

15/09/2005, 12:15

Oral

The front end electronics of the ATLAS Liquid Argon Calorimeter is powered by DC/DC converters nearby the front-end crates. They are fed by AC/DC converters located in a remote control room through long power cables. The stability of the power distribution scheme is compromised by the impedance of the long interconnection cable, and proper matching of the converters dynamic impedances...

137. Compact Data acquisition and Power supply system designed for hostile environment condition concerning radiation and magnetic field

Mr Stefano Petrucci (CAEN CAEN S.p.A., Via Vetraia 11, Viareggio, Italy)

Radiation and Magnetic Tolerant Components and Systems

Oral

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...
