<br />
* Discussion about the next steps to prepare a document addressing all recommendations from the report - this is required to get the green light for scheduling<br />
<br />
* Action items for addressing recommendations:<br />
::* (1) Draft run plan (order settings, calibration procedure for experiments)<br />
::* (2) Magnet: test will be scheduled summer/fall 2020; prepare a table of real parameters magnet (Steven L., Paul B.); finalize test in lab at low current - requires OSP - plan to submit in week 10 June<br />
::* (2) Calorimeter: make table with all parameters; already tested divider under radiation up to 150 krad (Hamlet's paper), quartz fiber not an issue; fibers and LEDs will be tested at Orsay <br />
::* (3) Estimates anode current for NPS and linearity; stay below 1mV (power supply issue); also note additional comments on post-ERR questions below<br />
::* (4) Admin<br />
::* (5) Admin<br />
::* (6) Admin<br />
::* (7) Verify that Pavel took into account radiator - also note that J/Psi experiment just ran in Hall C with that same radiator; Pavel can calculate activation doses in principle; GEANT4 estimate of doses at NPS electronics already exist<br />
::* (8) Draft overall software development plan; simulation of trigger to demonstrate that highly efficient on cluster sums and not dead due to background - can be done with GEANT4 (Alex C); add calorimetry contact people<br />
<br />
<br />
ADDITIONAL ERR QUESTIONS<br />
<br />
<br />
* MAGNET CONTROL<br />
::* Calculations show that magnet trip does not significantly impact beam line/dump - never goes anywhere to be concern for accelerator<br />
::* Hall C should be able to control magnet - get approval from Jay Benesch for this<br />
<br />
<br />
* CALORIMETER <br />
::* Label 30 Gy/h and line shown in ERR slides inconsistent - clarification: line is in the wrong place<br />
::* Discrepancies Pavel D. calculations and GEANT4 in particular at small angles - need to find out why dose/background rates so large in GEANT4 --> check; also affects ERR report #3 item<br />
