SummarySummary

• Background / previous CAEN HV/LV activities

• Birth of the EASY System• EASY specifications• EASY modules• EASY integration in DCS


3

BackgroundBackground

• CAEN’s Power Supplies R&D activities in the last 8 years:– SY1527/2527 family– OPC Server for the SY1527/2527 – SASY2000 for Radiation Tolerant and Magnetic Field

solutions tested working devices up to: • 7 kGauss• 1*1011 p/cm2 TD - 15 kRad TID• 2*1012 n/cm2 TD

• Result: – existence of a series of building blocks for a new

power supply concept

Why the EASY ?Why the EASY ?

• The LHC experiments need common solutions:– Reduce R&D costs (Hardware & Software)– Reduce Hardware/Software proliferation:

• Use of the same crates for all Sub-detectors• Use of the same modules where possible• Use of a Common Control System

– Reduce Maintenance costs:• Use of Common spare units

• CAEN proposes a “catalog” approach with a limited set of modules
