| July 12 | Justin Belicki | Self-encoding Electro-Permanent Magnets | Inductors are complicated and permananet magnets doubly so. Justin reports on a clever method to encode a magnetic latch with no additional parts. |
|---|---|---|---|
| July 19 | TBD | ||
| July 26 | Pavan Bilgi | Concurrent Clocking | Pavan shows off a magic trick that makes most of the parallel transfer overhead disappear and reveals his next trick which will be to make charge traps disappear. |
| Aug 2 | Michael Feeney | JT Cooler Survival Guide | Michael tells how we escape from the grips of Polycold, an unreliable and expensive supplier, by developing in-house capability to diagnose and fix Cryotiger problems, find alternate sources, and refurbish used parts. |
| Aug 9 | Roger Smith | Vacuum Advice | What's important? What's not? How much to pump and how seldom. Initial cleaning and baking. Use a leak detector as your pumping station, but don't do stupid stuff. Cold traps. Underlying physics. Vital roles of getters and desiccants. Gauge types and ion pumps. How your cooling system affects all this. |
| Aug 16 | Smith or Kaye | Waveform Definition Language | We have a powerful new tool, a Waveform Compiler that interprets timing rules written in any order the user sees fit It configures the controller to make those waveforms happen, or plots them on a screen in a matter of seconds. At the same time the tool keeps the host software informed so detector engineer has a single point of control. |
| TBD | Steve Kaye | Optmizing the ZTF pixel timing | Squeezing the most out of the pixel time to maximize noise averaging at 1 MHz pixel rate, or to go even faster. POSTPONED so we can include some interesting new discoveries. |
