Previous Day

  • Lab in-personnel: Luke, Himangshu
Status Run 82 In Preparation
Source mover Tests at room temperature
1300 Set X=-32, Y=96, source is about to hit the endstop
1301 Move it towards endstop. X=-34, Y=96. Saw a slight movement, no reading in endstop resistance
1304 Move it towards endstop. X=-38, Y=96. Saw a slight movement, reading in endstop resistance to 500ish ohm. This corresponds to -72 deg, -180 deg alpha/beta
Moving Y arm towards endstop == Lowering the valve to about 43 which will be 80 deg
1310 Move it towards Y endstop. X=-38, Y=64. Saw movement to about 120 deg as expected
1310 Move it towards Y endstop. X=-38, Y=45. Saw movement, no resistance value in Yendstop
1330 After multiple small moves around 43, finally saw resistance of 2 kohm when Y=20
1345 Lets return to initial position
1310 Move it away from Y endstop. X=-38, Y=96.
1310 Move it towards Y endstop. X=-38, Y=22. Small blip on the multimeter when it stopped, but no reading. Reading when Y set to 18
1310 Move it away from Y endstop. X=-38, Y=96.
1310 Compare initial position after multiple moves to the Y endstop
Since X=-38 lead to a complete touch on the Xendstop (equivalent to -72 deg), we expect 180+72 = 252 deg to be the touch point on the other side of the Xmotor arm
1304 Move it towards Xendstop. X=134, Y=96. The arm moved to expected location but it was quite vibration on the way and it bump on the endstop, small blip in the multimeter as well
Return to initial position , X=-38. Same vibrational movements and three touches on the endstop at the end. Blip in multimeter
