Evatronix as industrial partner

MC-Pad Kick-Off Meeting, CERN, Geneva, Jan. 13-14 2009, C.J. Schmidt and M. Idzik

                                                                                    

Two different approaches

Project driven: Very active VLSI ASIC development group integrates an ESR into a challenging electronics development for an international detector project:

AGH has taken over the readout electronics development for the ILC LumiCal

Forward Calorimeter

Application driven: Cutting edge diamond detector application development seeks ER for a generation transfer of knowledge in high speed microwave analogue ASIC electronics from highly specialized expert to step down soon.

Proceed with the PADI diamond detector pixel readout multi channel ASIC

development by Mircea Ciobanu who will retire at the end of 2009.

LumiCal

                                                                                    

LumiCal architecture

Single detector layer24 azimuthal sectors,each sector with ~64 radial pads

Si/W sandwich calorimeter, 2 half barrels, each 30 layers

Each layer consists of 0.35cm thick tungstenand 300µm thick Si sensor

Signal: from 2 fC – 10 000 fC

Occupancy: up to ~20%

Sensors: Cdet10-100 pF

Inter bunch time ~ 350 ns

                                                                                    

LumiCal Readout System

                                                                                    

Prospective ESR activities (recruitment in progress)

VLSI design, simulations, layout

Analog Front-end

Data conversion

Digital readout

Prototype ASIC testing

FPGA digital readout

Precise weighting of activities will heavily depend upon personal preferences, experience and capability of the ESR

Summary for ER engagement on WP11 at GSI

Deep fundamental technological research with important implications to detector system performance! pixelized diamond detectors for start and t0 (t < 30ps)

further broad applications with RPC TOF detectors

Pick-up and expand on Mircea Ciobanu´s first PADI 4 channel prototype before he leaves to Rumania for his pension. (Mircea is GSI´s in house Visiting Scientist)

Close interaction with a powerful analogue ASIC development group essential for persistance of this work and technology transfer. MC-Pad is a well matched vehicle!
