 Tue Apr 19 19:09:25 2016, James Bynes, Instructions, Obtaining data from XRM development boardstack 
|
Here are the instructions to obtain data from XRM boardstack. This has currently been tested with 1 carrier board, but little modifications will allow multiple
boards. Currently the data
taken is raw data, a pedestal extractor is currently under works.

|
Here is a data dump of everything that happened on the asus laptop while getting the laste 2015 / early 2016 incarnation of the XRM tested before being
delivered to KEK on the weekend of January 24th. Everything was done in bash and the firmware only addressed one carrier at a time, so the purpose
of this elog entry is simply to archive the information. |

|
Following up on James` suggestion, have posted transcript of compilation log below.
Not sure if there is anything should worry about here.
Strangely, the ton of warnings saw the first time I tried went away... |

Wed May 18 01:13:55 2016, Chris Ketter, Gary Varner, analysis, first data sets 6x
|
After getting data logging earlier in the day, Chris installed the detector and we took a look at data.
The amp board gain is set to lowest setting. Still, when looking at pedestal subtracted data, the preamps were picking up clear noise.
This may have impacted the pedestals, which were still noisy with preamps off, but long cables/detector connected. |
|
Wed May 18 21:32:21 2016, Gary Varner, noise during RF conditioning(?), carrier 0, asic 0
|
There is bursts of noise seen in the longer record lengths (1).
Some channels are quieter (2), though all see hints of 500MHz (3).
Channels 6&7 have pick-up that looks very much like 500MHz. (4). |
|
Thu May 19 02:08:09 2016, Gary Varner, analysis, statistics during RF on run
|
Summary statistics for short [1 run @ 64 windows] (1) and longer [100x] (2) show rather similar responses, where channels 6&7 are clearly noisier,
while all others are in decent agreement.
It becomes clearer in the larger statistics that the distribution looks bimodal. This could be due to amplifier chain instability/oscillation. |

Thu May 19 13:49:23 2016, Gary Varner, data taking problem report, morning 20-MAY-2016 JST
|
After beam came back on overnight, wanted to get a background reference data set.
However when trying to log data via GUI, the trigger number wasn't incrementing, nor a non-zero .bin file being created.
Restarted the GUI and confirmed that registers could be read, but still no response to triggers. |

Thu May 19 23:01:35 2016, Gary Varner, analysis, first try
|
Started a 1Hz run and let it run, the tail end of which might have had the detector in the xray beam.
Stopped run, but the GUI crashed when trying to close the very large (>1.5k event) run.
Large files bit unwieldy to work with, but first time series plot for channel 0 attached (1). |

|
Attachment 1 is a block diagram of the XRM setup for the Low Energy Ring (LER). Physically, this is located underneath the right wing of Fuji Hall,
tens of meters away from the crossing point of the beams (180deg around ring from interaction point). Directly upstairs is the optics hut where the readout
PC is located. |

|
After a battle to sort out the networking issues with the APC (on loan) and PDU, able to get all working fine, and logged in separate Elog.
The ability to power cycle XRM proved essential as periodically something is happening in the tunnel which causes the network connections (both
for XRM and APC) to get cycled. |

Mon Sep 30 09:36:16 2019, M. Andrew, documentation, measurements of accelerator clock and revolution marker
|
Following Nuclear Instruments and Methods in Physics Research A 499 (2003) 138–166, we know that the distributed accelerator clock is 508.8875
MHz (508.91 MHz measured) and that there are 5120 RF buckets. So the revolution marker should come at 99.3921 kHz (99.39 kHz measured).
Furthermore, it should be noted that the revolution marker is a 50% duty cycle NIM signal and the accelerator clock is about 600 mVpp. |

The firmware running on Althea/RAFFERTY https://github.com/mzandrew/hdl/blob/master/verilog/src/mza-test032.pll_509divider_and_revo_encoder_plus_calibration_serdes.althea.v
takes a 508.8875 MHz clock input, and uses a PLL to generate 4 phases of a 127.221875 MHz clock (input/4). Then it uses a 4-bit iserdes on the input
clock to register the phase of the revolution marker on the output clock. It takes about 1 second worth of these and populates a histogram. |
