Documentation With so much going on critical to document recently has fallen behind Update the People section to include bios and work experience: This can be a very nice

26 Documentation With so much going on critical to document recently has fallen behind Update the People section to include bios and work experience: This can be a very nice pointer to work experience in your future I routinely get asked for recommendations and it is useful to have something in the public domain 25

27 Publications Many of the projects are of great interest to outside groups 3x papers recently: CAP pixel (NIM A, IEEE/TNS), GEISER (accepted by NIM) Continually getting reminded to publish this stuff publish or perish Excellent opportunities: This can be a very nice pointer to work experience in your future If interested in an academic career, such publications are essential With students coming and going, a natural way to provide continuity for ongoing efforts LABRADOR paper TOF readout electronics (comparing Time Walk Correction techniques) 26

28 Cross-Training Thanks! Lab Interaction Encourage you to learn about what each other working on Very useful to be able to share ideas Lab Basic Training General Lab procedures (safety training! notebook, documentation) Electronics (handling, reading schematics, parts id) Soldering and hand wiring Computer usage Clean room (wire-bonding, materials handling) 27

29 Preview of Coming Attractions Ongoing projects Student Opportunities!! Success depends on you Other opportunities Jr./Sr. research projects [e.g. GEISER, CuEval] Directed study/nasa Space Grant/ROU (Japan/China) Publications (NIM/IEEE articles for RadFETR, CAP3, ) Board/firmware/chip design (PHYS476) Many designs in queue; SATURN, D RITOS, and pixel chips Design, layout, simulation and test opportunities Thoughts on how to improve things always welcome 28
