Collaborations Collaboration R&D –Gives a view outside the usual lab life. –Notice of experience, skills, expertise and knowledge at other laboratories, institutes and universities. –Broadens the spectrum, shows other perspectives and solutions on same and similar problems. –Initiates new ideas and solutions! –Give opportunities of beam studies at other facilities, meet colleagues under “real-world” (not workshop) conditions. –Social and cultural aspects, e.g. meet new people, travel, have some fun (at and after work!), etc. –Make comparisons (at many levels). 11/22/2008Summary: Project X Instrumentation WG15

Instrumentation Collaborations Beam instrumentation is quite ideal for collaboration projects: –Small and mid-size projects, ideal for smaller lab teams, university groups, etc. –Challenging, practical projects in beam physics and engineering, apply various state-of-the-art technologies, e.g. RF & microwave electronics Lasers and femto-sec timing precision mechanics, UHV, clean-room technologies digital signal processing, real-time software, etc. –Does not need a very large budget (unlike magnets, SCRF cavities, high power RF and modulators, etc.) –But: May require test accelerator facilities with beam time for beam studies. 11/22/2008Summary: Project X Instrumentation WG16

Definition of Collaborations Needs a very clear plan: –Exact definition of the R&D project Detailed instrumentation specs Scope and deliverables (can be anything between consulting and a complete turn-key system) Schedule and milestones Hard- and software integration Realistic cost estimation (M&S, SWF) –Identify individuals of both partners to be responsible to carry the project. Requires transparency and trust! –Needs oversight, control and reviews with expertise.
