Documentation
Most of DOM Integration Documentation has been prepared for the DOM Integration review of last December. All files are stored on GD.
All the documents are included in a MASTER DOCUMENT
File name is KM3NeT_DOM_2016_002-DOM_Integration_Documents
Current version: v5
This document lists the applicable and reference documents for the integration of Digital Optical Modules (DOMs) of KM3NeT Phase-1.
Applicable Documents
Reference Documents
For each document the filename on GD, the version number and the last DCR are reported

DCR: KM3NeT_QA_2017_104-DCR-NAP_002_DOM_Acceptance_test_v1
List of changes:
AHRS FW version field added
New Calibration document reference
New version is not yet available. The final decision on the corresponding DCR is suspended
Discussion about the DCR has not been completed. Investigation is still ongoing.
Based on PMT test statistics, the PMT group suggested to set the dark counts limit during the acceptance test to 10kcps
Current DOM production in Nikhef is done with Erlangen PMTs (not tested). Many NCRs around.
In order to take into account this, the following proposal has been submitted to the SC:
Dark noise limit during acceptance test set to 10kcps
verification of “tunability”: enlarge the acceptance interval
Investigation for a final decision has been completed, updates will come soon.

9. DOM Integration Master document D. Vivolo - DOM Integration Meeting
What can be added
What is still missing is documentation for non-standard procedures:
- re-opening of DOMs
- separating DOMs from the VEOC
- re-closure of DOMs (external pressure gauge)
- re-calibration of AHRS/Compass – done

New proposals
DOM Integration software
Integration of functional and acceptance test sheets inside the KM3NeT DOM Integration software (fill a window instead of an excel file). Advantages:
data will be sent directly to the DB
automatic log
the excel file will be automatically produced (then it must be loaded on the elog)
communication with the DB will be authomatized (no more python script) ONGOING
check of CLB calibration details will be included
automatic production of NCR, too! And automatic communication with the DB
Database
Integration of SRS inside the DB. This will help a lot with the documentation
Every other idea is welcome!

Quality
NCRs
Discussion about NCRs is now possible, some items needed more investigation.
Nikhef issues
ToT for untested PMTs
Dark noise for untested PMTs
High rates in DOMs produced by some PMTs
FPGA cooling
pressure gauge during DOM re-closing
clock reset
some of these items are still under study
New rules for documentation
Shipment of DOMs requires some actions. A discussion has already been started.
Agreement on possible actions
Procedure must still be written
ISRs will be adequately informed on new rules.

Miscellaneous
Distribution of components
Will start to be operative just after this meeting.
Need an inventory from all sites. Already available:
Nikhef
Napoli
well…Strasbourg and Nantes!
Distribution will be arranged according to the plans for autumn DOM production. Discussion will be done after the reports from DOM integration sites
Call for technicians
A joint effort is now mandatory to finally solve the Dom closing issue. Drawing and cost estimate of the DOM closing table currently used in Amsterdam are available. We need to re-design the tool in order to have lower cost while keeping all the functionalities. Please ask your groups (or your local services) for volounteers.

Miscellaneous
DOM Integration workshop
Open a doodle, let’s start discussion.
Guidelines about organization.
3 days for technicians (ISR must attend as well):
Training on ALL the phases o DOM integration
Done on a proper number of DOMs at different integration stages, in order to avoid waiting times
2 days for ISR’s only: safety rules, DOM testing, DOM integration software, quality….
The candidate site for the workshop is Nikhef. Naples is the only other possibility (also Ctania if it will pass the QA/QC inspection)
The candidate period is October (after the CM).
We should check compatibility with mass production stress tests. Discussion at SC for priority level (high, in my opinion)
An accurate preparation phase will be needed. A call will be done
Possibly, an additional training for “non-standard” operations should be considered
