Magnetic Measurement Facility readings of pucks, Steel () and Molybdenum --> media:LDGT01 Puck Measurements for MOKE 16-7-28.xlsx
Important INFO to note
- foil surface diameter across is 11 mm +-.5 mm
- Laser dot diameter through polarizer to foil surface is 2mm +-.5 mm
Excel Sheets for MMF data taken
---First, Data taken with original setup. Stage untouched since the 28th. Before stage was realigned in an attempt to be parallel with foil
- two measurements were taken
- Center was approximately 10.75 mm (on micrometer)
- at 9.3 mm (on micrometer) a tad left of center
- at 7.0 mm (on micrometer)
--- adjustments made on linear stage in an attempt to gain parallel relation to foil, We moved legs of table to be parallel with solenoid.
Note: Center at 12.8 mm
- far right 17.3 mm (on micrometer)
- media:farright17.3mm.xlsx
- This is not pretty^
- right center at 15.4 mm (on Micrometer)
- at 12.8 mm (on Micrometer) w/ lens... Note: I did not finish this measurement or foolishly did not save it...
- at 12.8 mm (on Micrometer) w/out lens... this was a test to see if the lens was the reason for the "dip"... As soon as we saw a dip we agreed the lens was not affecting signal therefore we didn't finish the measurement
- With mirror in place of foil at center 12.8 mm
- 25 amp increments (as opposed to 50 amp inc.) at 12.8 mm (on micrometer)
- Stability check at 12.8 mm (on Micrometer) with constant I of 200 amps over span of 16 min
