ROC10 of M1546 has 107 pixels with trimming problems:
in a VCal threshold scan after trimming 81 has a threshold underflow, means <0, and 26 pixels are outside 40-60VCal window (around Vcal 50) at +10C only.
Trimbit distribution looks reasonable.
It has been checked that using trimming parameters VCal threshold distribution is fine (checked at +20C). See plots attached:

A special test of M1630 only at +10C and with CtrlReg 17 showed no problem.

Tue May 26 23:00:50 2020, Dinko Ferencek, Other, Problem with external disk filling up too quickly
|
The external hard disk (LaCie) used to back up the L1 replacement data completely filled up after transferring ~70 GB worth of data even though its capacity is 2 TB. The backup consists of copying all .tar files and the WebOutput/ subfolder from /home/l_tester/L1_DATA/ to /media/l_tester/LaCie/L1_DATA/ The corresponding rsync command is
rsync -avPSh --include="M????_*.tar" --include="WebOutput/***" --exclude="*" /home/l_tester/L1_DATA/ /media/l_tester/LaCie/L1_DATA/
It was discovered that /home/l_tester/L1_DATA/WebOutput/ was by mistake duplicated inside /media/l_tester/LaCie/L1_DATA/WebOutput/ However, this could still not explain the full disk.
The size of the tar files looked fine but /media/l_tester/LaCie/L1_DATA/WebOutput/ was 1.8 TB in size while /home/l_tester/L1_DATA/WebOutput/ was taking up only 50 GB and apart from the above-mentioned duplication, there was no other obvious duplication.
It turned out the file system on the external hard disk had a block size of 512 KB which is unusually large. This is typically set to 4 KB. In practice this meant that every file (and even folder), no matter how small, always occupied at least 512 KB on the disk. For example, I saw the following
l_tester@pc11366:~$ cd /media/l_tester/LaCie/
l_tester@pc11366:/media/l_tester/LaCie$ du -hs Warranty.pdf
512K Warranty.pdf
l_tester@pc11366:/media/l_tester/LaCie$ du -hs --apparent-size Warranty.pdf
94K Warranty.pdf
And in a case like ours, where there are a lot of subfolders and files, many of whom are small, a lot of disk space is effectively wasted.
The file system used on the external disk was exFAT. According to this page, the default block size (in the page they call it the cluster size) for the exFAT file system scales with the drive size and this is the likely reason why the size of 512 KB was used (however, 512 KB is still larger than the largest block size used by default). The main partition on the external disk was finally reformatted as follows
sudo mkfs.exfat -n LaCie -s 8 /dev/sdd2
which set the block size to 4 KB. |

Mon May 25 16:58:23 2020, Andrey Starodumov, XRay HR tests, a few commments
|
These is just to record the information:
1. measured hit rates at which Efficiency and Xray hits Maps are taken are 40-50% of the 50-400MHz/cm2 that in the titles of corresponding plots
2. in 2016 the maximum rate was 400MHz/cm2 but with such rate (or better corresponding settings of HV and current of Xray tube) in double columns of certain modules (likely depending on a module position with respect to Xray beam spot) the measured rate was smaller than 300MHz/cm2 that is target rate. Somtimes extrapolation of efficiency curve to 300MHz/cm2 is too large. I think this is not correct. Unfortunately higher rates cause too many readout errors that prevent a proper measurement of the hit efficiency. May be a new DTB with than 1.2A maximum digital current will help.

Krunal proved test result of four modules and Dinko analised them.
M1630: Grade A, VCal calibration: Slope=43.5e-/Vcal, Offset=-145.4e-
M1632: Grade A, VCal calibration: Slope=45.4e-/Vcal, Offset=-290.8e-
M1636: Grade A, VCal calibration: Slope=45.9e-/Vcal, Offset=-255.2e-
M1638: Grade A, VCal calibration: Slope=43.3e-/Vcal, Offset=-183.1e-
A few comments:
1) Rates. One should distinguish X-rays rate and the hit rate seen/measured by a ROC (as correctly Maren mentioned).
X-rays rate vs tube current has been calibrated and the histogramm titles roughly reflect the X-rays rate. One could notice that
number of hits per pixel, again roughly, scaled with the X-rays rate (histo title)
2) M1638 ROC7 and ROC10 show that we see new pixel failures that were not observed in cold box tests. In this case it's not critical, since only
65/25 pixels are not responcive already at lowest rate. But we may have cases with more not responcive pixels.
3) M1638 ROC0: number of defects in cold box test is 3 but with Xrays in the summary table it's only 1. At the same time if one looks at ROC0
summary page in all Efficiency Maps and even in Hit Maps one could see 3 not responcive pixels. We should check in MoreWeb why it's so.
4) It's not critical but it would be good to understand why "col uniformity ratio" histogramm is not filled properly. This check has been introduced
to identify cases when a column performace degrades with hit rate.
5) PROCV4 is not so noisy as PROCV2, but nevertheless I think we should introduce a proper cut on a pixel noise value and activate grading on
the total number of noisy pixels in a ROC (in MoreWeb). For a given threshold and acceptable noise rate one can calculate, pixels with noise
above which level should be counted as defective. |

A few extra adjustments were made in:
38eaa5d6: also removed double-counting of pixel defects in module maps in the production overview page
51aadbd7: adjusted the trimmed threshold selection to the L1 replacement conditions |

M1539: Grade B due to mean noise >200e in few ROCs
M1582: Grade B due to mean noise >200e in few ROCs and at -20C 137 pixels in ROC1 failed trimming. For P5 could use older test results (trim parameters) of April 27 M20_1 when only 23 pixels in ROC1 failed trimming
M1606: Grade C due to 161 pixels failed trimming in ROC2 and total # of defects in this ROC 169. For P5 could use older test results (trim parameters) of March 19 M20_2 when only 36 pixels in ROC2 failed trimming or April 6 when 40 pixels failed (at all T this test has the best performance). |
