Plan

  • Focus scan
  • Rotation scan
  • Lens vertical scan
  • Iris scan
  • Quad Scan
  • Filter scan

  • Different binning
  • Different lens side

  • Final quad scan

20:05 Start

  • beam tuning
  • load optics: set13mar01_1357.dat
  • Initial Parameters:

binning 3x3

otrlensz 13.5

otrm1x 4.2

otrm1y 3.6

otrlensy 5.5

otr_iris 26.184

charge 0.6 *10^10

filter 4 (550-40)

lens CVI LAO - 120 - 30

  • Magnification factor

Lens Magnification FactorSorted ascending
BLB 30 120 PM 7.39
CVI LAO 120 30 7.40
DLB 30 100 PM 9.19
SLB 30 100 PY2 9.13

Focus scan

  • Start: 10, stop: 13, step: 0.5

Super good result but not enough resolution -> change binning to 3x1

  • repeat focus scan, start from 11, to 11.7 with 0.07 mm step
  • Best focus position: 11.35

Quad scan

  • QM14FF Initial current: -91.92 A
  • Start: -85, stop: -95, step: 1 A
  • Best position: 91.74
  • sigma: 1.50551 +- 0.02815

Iris scan

  • Start: 26.184, stop: 5.800, step: 1.568 mm

Filter scan

Many modulator trigger interlocks

Rotation scan

  • Initial 2.13
  • Start: -4, stop: 8, step: 1

change lens to DLB-30-120-PM

Do the same set of scans

Focus scan

* Start: 11.6, stop: 12.6 , step: 0.1; best focus position: 12.1 mm

Lens vertical scan

  • start: 4.5, stop: 7, step 0.5 return to 5.5 mm
  • take 10 images at focus lens position = 12 mm.
  • move otr:lens:z lens vertically to 7mm and take 10 images
  • move otrm1y from 3.6 to 4

Quad scan

  • Initial current = 91.74
  • Start: -85, stop: -96, step: 1 A
  • Best position: 91.76
  • sigma: 1.6406 +- 0.033

Iris scan

  • Start: 26.184, stop: 5.800, step: 1.568 mm

Filter scan

2D Filter scan (i.e. focusing scans for different filters):

  • Focus scan 550 40
  • Focus scan 500 40
  • Focus scan 500 25
  • Focus scan 550 25
  • Focus scan 600 40

change lens to DLB-30-100-PM

Focus scan

  • Start 11.11, stop: 11.27, step: 0.02
  • Focus position: 11.19

Quad scan

  • Initial current = 91.76
  • Start: -88, stop: -97, step: 1 A
  • Best position: 91.66
  • sigma: 1.79698 +- 0.06098

Iris scan

  • Start: 26.184, stop: 5.800, step: 1.568 mm

Filter scan

change lens to SLB 30 100 PY2

Focus scan

  • Start: 8.9, stop: 9.6, step: 0.1
  • Focus position: 9.19

Quad scan

  • Initial current = 91.66
  • Start: -88, stop: -97, step: 1 A
  • Best position: 92.54
  • sigma: 2.42 +- 0.07
