Petal needs in B180

Petal needs in B180● Petal schedule is far behind stave schedule● Most likely no full Petal before production starts● We may want to test smaller structures addressing Petal specific

issues, eg Petalino

8.60 cm

8.07 cmUse 4” wafers. Eventually use real size sensors (either wedge or barrel-type)

Petal needs in B180● The small object we will make (now dubbed Petalino) won't be ready

before fall of 2011● Full size wedges will not be ready before 2012● We would be interested, however, on a small corner with access to a

DAQ setup for running the Petalino● Dark box● HSIO access● Cooling (chiller with circulating anti-freeze, access to Nitrogen )

● Thermo-Mechanical tests are being done in IFIC-Valencia, NIKHEF and DESY

● If fancy equipment available, a disk (or disk sector) mock-up would be interesting but it would require 64 dummy petals....


Forward Efforts relevant to B180

● Some groups (DESY, Freiburg, NN) will build a limited number of barrel modules

● Have bought sensors● Receive hybrids from Liverpool

● Original motivation is to gain experience● These modules will be contributed to the STAVE 09 programme


Manpower Contribution from Forward Groups

● Poll for contributing effort was made after last EC sensor meeting

● Received the expected contributions listed below● NB: for the analysis students involved this is meant to be

service work (class 3 OTP), and it should be recognised as such● DESY (Zeuthen):

● PhD student from April 2011 for 3+3 months, 0.8 FTE (Conrad Friedrich)

● Berlin (Humboldt), works closely with DESY-Zeuthen: ● Postdoc June-July 2011 with 0.5 FTE (Malik Aliev)

● Freiburg● PhD student from about now for 6months 0.3 FTE (Liv Wiik)
