+Update for all the stuff that happened last week and yesterday.
+For the Students and their imaging:
+  * after some struggle to understand the magnified diffraction rings. we choose to image larger pin holes(200um, 100um, back to 50um)
+  * we found at larger pinholes, we could determine the edges better, and gain a better frame of reference as we move back to the 50um pinhole
+  * we found the focus of the 50um pinholes, and then place in a 3mm tube.
+  * with a lot of alignment, we got the exiting light at the focus and could see the diffraction and the size of the whole
+Inlite Laser Update:
+  * Gil swapped the laser head, and found it didn't have the doubling crystal.
+  * What we thought was the doubler was just a filter for the 532nm light.
+  * On Friday we used the laptop software to adjust the Eff , but to no avail.
+  * on Monday(yesterday), Chris help Gil found out the doubler was missing a Waveplate so we were actually changing any polarization
+  * Placing this WP in, 532nm spiked.
+  * Gil placed the laser onto the mounts and start the alignment through the AMP
+  * we found that the laptop will Hard Code certain value, like if Trigger is EXT or INT
+  * that needs to change with the laptop before plugging to the computer.
+  * Also, the Pointing Vector of the laser onto the Regen Crystal changes the wavelength effect, So resetting the Mazzler(Cuts off wavelength) will help.
+  * When it come to the Delays. The Pockel Delay is the Q-Switch Delay. And we don't adjust that
+  * we only should adjust the Flash Delay(near 545500ns)
+  * We adjust 1 mirror for the Inlite laser alignment and 1 WP
+  * we adjust 1 mirror for the Stretched Oscillator beam
+  *

+Gil got in early, and ran a Q3xQ1 runs with thick acrylic.
+im trying the same runs, but with 3.5mm step size. First set with 4mm Teflon(550keV Stopping) then 6mm teflon(700keV stopping).

 I ran simulations on the different quadrupoles configurations.On my personal laptop Jupyter. We physically test Quad1 with 2,1, then 3 magnets per pole, then Quad1 with 3 and Quad2 with 1 magnet. Look for the times started to know when each starts. as well as the image to know when the Quads are Flipped up or down.
 we used the Teledyne_3 (Off Brem)
