This file is runids, with a chronological listing of all runs, plus notes.

Test Configuration:

 
FPC FPC S/N Window Blocking Plate Preamp Amp MCB
fpc_x2 410148 030 circ37_x2 004 001 204
fpc_hn 410144 020 rect36x99_04 005 008 200

On Tue Dec 2, the stage positions required to place the centers of  the FPCs on the beam were estimated by eye to be:
 
 

FPC y-stage z-stage
x2 31300 -31400
hn 31300 44823
 

Through Dec 4, the ULDs on the ratemeter SCAs did not work, so the logged rates include the pulser peaks, at around 300 Hz. The amplitudes for both test pulse generators were adjusted using manual settings.

The ROIs for .sum files were set to channels 10-400 for all runs. Note that for runs after 501051 the pulser peaks were lowered to channel 350 so the .sum files will include the pulsers.

The SX700 beam was first available around midnight Dec 3/4.  The first action was to improve our estimate of the center of each FPC by "manually" moving the 4 edges of both FPC blocking plate apertures across a 330-eV beam and recording the ratemeter readings.  The improved center positions thus determined (by taking the average of the window edges) were:
 

FPC y-stage z-stage
x2 29300 -34630
hn 29720 41560
 

("hnedge" position set 14 mm lower at 27560)
The stage tables, $DB/ly.rdb and lz.rdb were updated at this time.

A beamline aperture of 50-um diameter was used (thru run 500754) to obtain the smallest possible beam size.

Here is a list of relevant runIDs for the Dec 4-7 SX700 runs at BESSY. Mistakes and setup runs, such as when adjusting FPC voltages to put the peak in the desired channel, are not included.

Due to a miscommunication, the position of the "hnedge" windowlet, located 500710, a detailed QE Map of that windowlet, was therefore done in the wrong place (using the old estimate of ly,lz = 29720,27560), off by about 500 um in y, and 40 um in z.  Most of the data should still be useful, however.

The next 4 tests were Beam Profile measurements, scanning the 330-eV beam across each edge of the fpc_x2 circular blocking plate aperture. 1dscans, 31 points, 40-um steps, 1200 um total, centered 18.415 mm (1/2 diameter of the fpc_x2 blocking plate aperture) from the aperture center.

The next 4 tests were supposed to be Beam Profile measurements, scanning the 500-eV beam across each edge of the fpc_x2 circular blocking plate aperture. Due to confusion, the step in which the FPC is moved 18.415 mm away from the center was skipped, and so the scans were conducted centered on the central windowlet.  Although these provide no beam profile information, they are very-fine-step QE Map measurements = 1dscans of 31 points in
40-um steps over a range of 1200 um.

Although the 930-eV Beam Profile tests were checked off on the CMDB/testlist as having been completed, they were apparently never done.  This was only discovered after we had returned from Germany.

500751 M-IXF-QM-1.090 0.930 x2 QE Map, 5x5 at center windowlet
500752 M-IXF-QM-1.091 0.930 x2 QE Map, more around center windowlet

500754 M-IXF-QM-1.093 0.930 x2 QE Map, samples of windowlet centers

Up to now we used the 50-um beamline aperture to get the smallest possible beam size.  We switched to the 600-um aperture for the Spectral Response Function measurements because the photodiode calibrations of beam intensity are more precise.  (Unfortunately, we forgot to switch back to the 50-um aperture at the end when we did the extra/repeat QE Map and Beam Profile tests.)

The SRF measurements also double as QE measurements since the beam intensity was calibrated at each energy to ~2% (??) by the PTB photodiode and the ring current was logged by a PTB computer.

SAO computer time is 2'56" behind the BESSY ring current logger time. Note that the BESSY times are in local time, while the SAO times are about 1 hour earlier since they are UT.

For all SR (Spectral Response Function) measurements, both FPCs collected data---one of them collected background.  The listed detector is the one that was exposed, which was always the "d1" detector, unless otherwise noted.

Many of these next SRF runs had several "sample collects" to adjust the voltage/peak setting, and they were just as long as the "real" measurements.  Those runs are not listed here, but if you want more counts at several voltage settings they are available (although you
may have to look at each file to figure out what was done since log book entries for these setup runs are sparse).  Typically there are 500,000 counts in each SRF measurement.

*Up to now the pulser peaks were around channel 470.  From this point they were lowered to channel 350 to include the pulser/x-ray pileup peaks. Since the ROIs for .sum files were set to channels 10-400 for all runs, the .sum files will now include the pulsers.

It was noted at this time that the "hnedge" position had not yet been properly determined or updated.  This was corrected by editing $DB/ly.rdb and lz.rdb to have hnedge at (29242,27520)

At this point we should have replaced the 600-um beamline aperture with the 50-um for the Beam Profile and QE Mapping tests, but forgot.  The beam was therefore much larger than for the first set of BP and QM msmts. This doesn't matter for the QM tests which sample QE at windowlet centers, but will make interpretation of BP data, and QM data collected at points not in the center of windowlets, more difficult.  Working in our favor, however, is the fact that the beam is wider horizontally than vertically, and most of the msmts after this point are vertical scans, so the beam isn't that much wider than before.

Note that results from the BP tests at 500 eV which follow cannot be applied directly to the earlier 500-eV QM msmts because the beam size is different.  We must ask PTB how beam size varies with energy--if it is not a strong dependence, then we may be able to apply the early 330 eV beam profile results to the 500-eV QM data.  In any case, the 330 eV data
is most important, and good and complete (there is just one msmt at 330 eV in this last batch)---the 500 and 930 eV data was supplementary.

End of SX700 testing using SAO detector chamber.

The second week of testing used the PTB reflectometer and photodiode to measure the transmission of filters (to be used on the white beam for absolute QE tests) and the HSI uv/ion shields.  All the data were collected by PTB.
