1. Infrastructure Equipment December 19, 2000

2. 2 Background To complete the work for the ATLAS detector, some additional equipment items are needed. In addition, there is heavy pressure from the ATLAS management for LBNL engineering to take on more responsibilities, tied to interests of Physics Division. Why? LBNL has talent. World-wide shortage of good engineering within even enormous ATLAS collaboration. US ATLAS funding is capped. Conflict between buying equipment and salaries. Solution: increase LBNL infrastructure => specific equipment items, which will become of general use to future projects. In short, we are here to beg for money.

3. 3 Specific Items(1) Automated probe station for production 8” integrated circuit wafer probing: $75K –Most future experiments will use 8” wafer technology –One such probe station at LBNL(Los Alamos project) –Extrapolating from previous(6”) experience…multiple 8” probe stations will be needed. Plasma etcher for oxygen or argon plasma cleaning: $20K(used) –Currently use system on campus. Not good enough for production items. –Of general use for projects that require wire bonding(clean surfaces) Precision impedance analyzer: $35K –Basic capability that does not exist for characterizing passive components(capacitors, etc) and for custom cables(eg. low mass flex cables made at LBNL)

4. 4 Specific Items(2) IR camera for thermography: $70K –Used for thermal quality control of thermomechanical structures. –More generally can be coupled with recently installed TV holography system in CMM area to have combined thermal imaging and “distortion” imaging. –Also can be used to look for “hot spots” in electronics boards and related. –Capability exists at lab but largely tied up in environmental studies. Thermal chamber for TV holography and IR thermography, if acquired: $30K? –Viewing mechanical distortions under temperature change requires thermal chamber for good control. Increased infrastructure for composites manufacture: $185? –Some funding for this ($95K) for this year –But missing autoclave for big items.

5. 5 How Well Are Costs Known? 8” probe station: multiple demos, have quotes Plasma cleaner: examples(very similar to one on campus) in used equipment catalogs. Impedance analyzer: catalog item, verbal quote IR camera: demo of models from two companies, have quotes Thermal chamber: ?? Increased infrastructure for composites manufacture: have numerous quotes for autoclaves THE TOTAL COST OF ALL ITEMS IS $??K.
