New Architecture:


FE TDC selection

-Howmuchradiation do we get

-Howmuchradiationcan the Proasic3E have


Actelversion, Wilcotalks

-results of prototypes

-proposed design


-Fiber setup-Services likesupplies, cooling


New architecture


Largersilicon inner area, sameamount of electronics

50% lessstraws , 50% Scintilating Fibers

We assume the scenario1 where we change all FE’s tonewonesnr 2 is lesswork and lesscostly


New Front Ends, new TDC selection

We need a new OTIS TDC with 40Mc output instead of 1Mc

To adapt the OTIS tdcthere was toolittlemanpower in the chip developmentarea

FPGA solutionscanbewithActelantifuse, ActelProasicor Altera

For the selectionof Commercial Off The Shelf (COTS) components we have to know the newradiationlevels

Radiation Test Proasic3E

2004 resultsSpecsproasic (in ourControlboxes)

(Notpublished, Saclay, Dominique Breton, JaquelFr.)

1.Programmable upto 17 kRad

2.Still funtionsuntil 30 kRad, then high current and malfunction)

2010-2013 Syracuseuni

Aboutsame as SPECS test above

-Ram few SEU every 3min run of few kRad-Flash rom dito

-Plltested end 2012 good chips increasingtdcerrors 20-37on 8*10^9 measurements per run of few krad

2 bad chips 3*10^9 (tdcvaluechangefrom 10>11?) a lockerroroccurredonly 1 time during all tests



The Proasiccanmeasure 5 bits withacceptable bin sizevariation


All proasictdc boards have to bereplacedafterseveralyears of running to beable to run for 10 years in radiation

Consequencesfor fiber installation and power in othertalks
