 +Nano wires without CD:
 +
 +800um raster steps
 +
 +Rastering started at 319538-755, again at 782-841, 843-3200056
 +
 +streak stopped at 319899
 +
 +rastering again t 320058-171
 +
 +
 +====05/13-15/2026====
 +
 +so I realized the I wasn't rastering and the short pulse created a hole in the Saph. 
 +
 +we test just a Saph window, and got the same results at the D2O/DTi.
 +
 +we moved to a lot of CD2 tape and CH.
 +
 +MIT Users left on Friday
 +
 +Monday we will take NanoWires
 +====05/12/2026====
 +
 +got everything ready to go, including the drilling in the code, but there was an iris closed so we had to vent. then we found cracks in the 200um glass, after a few shots. and went home for the day.
 +
 +====05/11/2026====
 +
 +did some drilling, but got a late start due to changing the delay from 53ns to 47.5ns(Steve said too). because we our saturating Frodo's signal, we never were at focus, so it took 5-7 shots to get a decent signal. Non signal on our PMT, but there was on MIT's
 +
 +====05/08/2026====
 +
 +I helped set up but I had to leave for Delanies birthday. they did both short and long pulse and get signal on our PMT. they learned that drilling with the short pulse 3-4 times was benefiting 
 +
 +====05/07/2026====
 +
 +I took shots of just the ring pulse, with variable delay times of the wedge laser. the particles were too dense and it was very hard to see. the goal was to see the shock

 MIT WEEK 2, FIRST HALF MIT WEEK 2, FIRST HALF
  
 +We did more shots on the CD2. Gil coded the rastering, so that we can zigzag cross the CD2 tape. we got 1  bubble on Monday. The PMT seems to be shorting when under vacuum. still idk why.
 +
 +
 +On Tuesday, we started testing the delay line and the long pulse. Gil made a telescope to better focus the delayed beam, so that it doesn't torch an optic. while I created a delay ling for after the compressor using 2inch optics. At the end, before the compressor was best. Since I took some 2inch mounts from the long path, Yun we created the long path with 1 inch optics and realigned everything. 
 +
 +I went to move the frame the holds the CD2 target out of the way, but ended up breaking the mount the holds the 35mm lens. I replaced it with the one the ucsd students were using.
  
 +On Wednesday, Gil got the fast diode set, so that we can see the timing between the wedge laser and long pulse. and he got the Frodo, auto focusing to work. We did some shots onto the CD2 foil, with only the ring pulse. But couldn't see any convergence of the ring. Yun created the nanoparticle target. I made reconnected the flipper motor to auto block and unblock the Frodo laser. I did some shots with just the long pulse onto the nanoparticle target. and I think I see convergence. Especially at 760,585,000 ps and 760,605,000ps delay.
