129.57.81.111:

present: Sergey Boyarinov, Sergey Pozdnyakov, FX, Nerses, Hovanes, Eugene Pasyuk

1. g14b: run started week ago, following problems were fixed:

* level2 cables connected under the CLAS

* several above-FASTBUS fans replaced, will continue

* several CPUs replaced because of PMC failures

* rate was 4 kHz at 85% livetime at 20nA beam current BEFORE level2 fixes, expecting improvements

* cmon works in electroproduction mode, see target; will calibrate and switch to photoproduction

* DC noise problem was investigated, Mac found and removed aluminum foil inside region 1, hopefully it will help

* remaining problems: SLM signel was broken - fixed, Moller should work;

2. Test setups:

* Hall D setup works, including silo part; must be ready to add tage and tage2 later

* HPS: ic is installed, connected to old ADCs, IP pedestal procedure works, FX looking at them; JLAB discriminators were installed (16 CLAS, 12 from Hall D), all software is ready to program them; FADCs are installed but not connected; trigger part must be restored (will try to do it in couple of days) and read IC out with CLAS but havinf separate trigger bit from IC; temperature control need to be restored; Nerses will test softioc for discr scalers, will need to replace cpu in pretrig3 installing intel cpu

== Test results : Calibration VX1290A with DSC2 ==

TDC Outputs from JLAB VME Discriminators DSC2 were Inputs for CAEN VX1290A.

Width of TDC Outputs changed from 4 ns to 40 ns.

Histograms present distributions for four CAEN VX1290A TDCs in each run

Test was done in Counting room VME crate "croctest2"

* In run # 10491 four VX1290A with Ser. ## 56, 60, 53, 55 were tested, TDCs were in slots 7, 8, 9, 10 correspondingly:

== Tests of CAEN TDCs VX1290N with NIM inputs ==

TDC Outputs from JLAB VME Discriminators DSC2 were converted on
ECL-to-NIM translator and were used as Inputs for CAEN VX1290N.
CAEN TDCs VX1290N and JLAB VME Discriminators DSC2 were tested
in Counting room, in VME crate "croctest2".

Width of TDC Outputs changed from 4 ns to 40 ns.

Histograms suppose to present distributions for four CAEN VX1290N TDCs
in each run, but in run 10514 only three VX1290N were tested.
In run 10516 - fourth TDC with Ser.28 was not visible in crate,
something wrong with setting of base address.

* In run # 10514 three VX1290N with original firmware v.0.5 and Ser. ## 22, 23, 24 were tested, TDCs were in slots 7, 8, 9 correspondingly:

[https://clonwiki.jlab.org/wiki/clondocs/Docs/tdc1290/1290n.Ser.22.23.24.00_10514.pdf 1290n.Ser.22.23.24.00_10514.pdf]

* Run # 10516 for four VX1290N with firmware v.0.6, Ser. ## 25 29 31 28 - slots ## 7 8 9 10, Ser.28 - had a problem, not visible in crate:

[https://clonwiki.jlab.org/wiki/clondocs/Docs/tdc1290/1290n.Ser.25.29.31.28_10516.pdf 1290n.Ser.25.29.31.28_10516.pdf]

* Firmware changed to v.0.6 for Ser. 22, 23 and 24. Address Cards were changed for Ser.28, now VX1290N Ser.28 PBCM0044 is visible in crate.
So, in run # 10520 four VX1290N with firmware v.0.6 and Ser. ## 22, 23, 24, 28 were tested, TDCs were in slots 7, 8, 9, 10 correspondingly:
