Integration in GTK Module
• Work space prepared inside the Divisional Silicon Facility (bldg 186)
• Dedicated Technical Student starts end of August
• Possibly one US Summer Student available before then
• Staystik: paste -> received; film -> sent from firm
• Also available: diamond-loaded SU-8 (spin-coatable in thickness < 1 mm
Diamond-loaded epoxy ME7159 from “Al Technology”

Infrastructure
Meeting agreed with EN/CV-DC on May 26th to start discussing detailed specs for the cooling plant (preferred option: cold liquid C6F14, scaled down from CMS PIX unit, single unit with 3 branches, controls under Unicos+PVSS)
1 rack needed in the cavern (exp. site visited on May 6th, preliminary requirements provided to Gilles Maire on May 17th).
Option A: rack in TCC8 + minimal distance from GTK– longer access time after dump
Option B: rack in ECN3 + shorter access time after dump– very long transfer lines
Open question: optimal position for controlling PLC?
