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.


Project Plan


ILC Luminosity Detector, c.f. WP6, DESY

LumiCal


LumiCal architecture

Si/W sandwich calorimeter,

2 half barrels, each 30 layers

  • Signal: from 2 fC – 10 000 fC

  • Occupancy: up to ~20%

  • Sensors: Cdet10-100 pF

  • Inter bunch time ~ 350 ns

Each layer consists of 0.35cm thick tungsten

and 300µm thick Si sensor

Single detector layer

24 azimuthal sectors,

each sector with ~64 radial pads


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


CVD Diamond Detector Material

Diamond,

a large bandgap semiconductor

 unsurpassed in signal speed

(28 ps time res. shown)

 enormous radiation hardness

Poly – CVDD:

size up to 4"Ø

d = 12µm–2mm

CCE ≈ 50%

SC-CVDD:

"standard": CCE = 100%

d =300-500µm; size=5x5mm2,

”advanced/special”:

d =40-500µm; size=10x10mm2

Single Crystal- CVD Diamond Detectors

for Spectroscopy and Timing

pixelized detector will allow GHz individual particle detection including essential timing information:

start, veto and interaction t0 determination


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 (dt < 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!
