Main topic of discussion

  • Shall we perform the cold test of the APAs (after integration with

Cold Electronics and Photon Detector) on the surface at the Integration and Test Facility or in the clean room outside the cryostat at SURF ? YES

  • Main advantage
  • Test performed at SURF after routing cables through the APA frames,

with two stacked APAs

  • As soon as the test is completed move the APAs inside the cryostat
  • Problems
  • Not a lot of space inside the clean room outside the cryostat (worse for

3rd detector to be installed)

  • How the hell do we get the LN2 required to operate the cold box in the

mine ? The installation of the cryogenic lines from the surface to the DUNE cavern is foreseen for later in the project

What Happens in the Cavern

  • Attach of upper and lower APAs (not in the clean room) with

connectivity test for the photon detectors

  • APA pair moved into the clean room, installation of Cold

Electronics cables including their routing through the APA frames

  • APA pair moved into the cold box, CE cables connected to

patch panel inside the cold box

  • Warm test, followed by cold test
  • APAs moved into the cryostat

New Layout of the Top of the Cryostat

  • Work to be done by Cold Electronics consortium
  • Need to finalize the routing of all cables/fibers to CUC
  • Understand cooling requirements for the power racks
  • Dimitar and Jack to provide a new set of integrated models

with as much details as possible

  • Additional work required on the facility side (move pipes

internally, mirror cryostat design, understand how we get the LN2 for the cold boxes)

  • Cryostat penetrations need to be installed as soon as the

iron structure of the cryostat is complete (advance procurement in the schedule)

Logistics and Databases

  • All the logistics involved with transport of parts for the cryostat

and the detector is not yet fully understood

  • Logistic coordinator for LBNF and DUNE has just started

working, need to understand and accommodate also our needs (we may not ship containers, we may ship a lot of small boxes too)

  • Role of databases still needs to be fully sorted out
  • Cannot just think of part breakdown structure, calibration during QC,

and logistic, need to have full view of database requirements throughout entire life of experiment, well understood list of requirements, before choosing database structure

Dust in the Cryostat

  • Long discussion about the amount of dust that can be collected

inside the cryostat (and its activity)

  • Requirements:
  • Feed clean air from the surface into the cryostat through the

manholes

  • All other feedthroughs to be closed as soon as possible
  • No special flanges (too expensive)
  • Cryostat penetrations need to be available early in the project, so that

we can use them to seal the cryostat

  • For cable routing reopen one penetration at a time, install clean tent

around the area that is open

Clean Room

  • The following slides are taken from Bill Miller’s presentation(s)
  • Bill has a detailed plan for the work that takes place in the

cavern that meets our requirements

  • The main problem is that in the current design the CPA

assembly tower location interferes with opening / closing the cold boxes

  • For the 3rd detector the space is even tighter (SAS moved on

the top of the bridge)

  • Some work still needed to demonstrate that we can assemble

and install the detector on the timescale of 8-9 months

Access #1

5 Nov 2018

  • M. Verzocchi | Report from the SURF Workshop
  • Since occupancy is less that 50 FTE/shift

access is via one permanent stairway. A second temporary one can be located on the east end of Cavern #1

  • Permanent stairs are located outside the

cleanroom and stairs next to the bridge in the “dirty” area

  • APA access is thru a removable panel in the

roof

  • Personnel access is via man-door into the

personnel SAS, a second emergency man- door exit could be at the bottom of the stairs

  • Fork-lift access is thru doors located in

Materials Handling SAS

  • M. Verzocchi | Report from the SURF Workshop
  • Materials Access for Detector #1

and #3 are shown in Red

  • Access to Detector #2 and #4 are

shown in Blue ALL materials are moved by SURF from the headframe area to detector halls or a location to be determined Delivery schedule is controlled and managed by SURF, carefully logistics management is required during ALL phases of DUNE A ~1 week DUNE materials buffer underground will help

Materials Handling SAS

5 Nov 2018

  • M. Verzocchi | Report from the SURF Workshop
  • The Materials SAS has several important features
  • Easily removable roof section
  • APA pairs are completely covered except for access to pick points
  • Assembly Tower allows stair access to make connections in the

middle and the top access to the other side is via scissor lift

  • Sliding barn door (or similar) for APA pair access to cleanroom
  • CPA boxes moved into SAS and moved via cleanroom fork lift into

cleanroom

If needed this could be a separate corridor to keep APA area cleaner

APA Assembly stations Detector #1

5 Nov 2018

  • M. Verzocchi | Report from the SURF Workshop
  • To meet the installation schedule of 3 APAs and 2

CPA pairs per week at the full rate we have 2 APA assembly towers and 1 CPA assembly tower

  • Assembly Tower 1-APA
  • This is where the 2 single APAs are loaded onto the

assembly tower using the cavern bridge crane

  • The two APAs are joined after PD testing and rolled

into cleanroom

  • Assembly Tower 2-APA
  • Has 2 work stations designed for cabling and testing

APA pairs-Repair spot for failed APAs coming out of cold box

  • Assembly Tower 3-CPA (APA?)
  • Uses hoist on shuttle beam/crane to move CPA

components in place

  • Tower could be designed to hold APA if needed

Cold Box & Stair Design Features

5 Nov 2018

  • M. Verzocchi | Report from the SURF Workshop

While the Cold Box has not been designed yet one of the key features is that they can move to the area between the cryogenic pumps

In this layout the egress stairs are now part of the personnel SAS

Installation Rate Dec #3

5 Nov 2018

  • M. Verzocchi | Report from the SURF Workshop
  • This is similar to the old version 7

installation plan

  • While we were able to add a 3rd work

station to the APA assembly tower 3.5m the Toaster Area is very congested.

  • In theory you could assume roughly the

same rate but there is so little work space you may have to do CPA and APA work more linear. It is not clear there is room for 20 FTE/shift. Best guess would be ~25% slower See talk on Detector #3 installation

slide-19
SLIDE 19

What else is New ?

  • Work inside the cavern now happens on a 2 shifts daily through

the entire week

  • The Cold Electronics group needs to provide the personnel for

the Friday/Saturday/Sunday shifts (that’s when the testing in the cold boxes takes place)

  • This means that the CE personnel needs to go through the full

training (1 week) for underground guides

  • Plan for deployment of CPAs to be revisited
  • The original plan was to deploy CPAs on a row by row basis
  • Now moving to deploy (even install) CPAs at a later date, allows for

more testing (repairs ?) of APAs in place

Cold Testing of APAs

  • APA production to start (UK) in the 2nd half of 2020
  • Will perform checks on first few APAs in the cold box at CERN
  • Will not have integrated tests in the cold boxes in the cavern

until 2024 (?)

  • Strong suggestion to perform cold tests after CE/PD integration
  • n a sample of APAs during production
  • Initial suggestion is to have cold boxes (and perform integration) at

the APA production facilities

  • This has significant personnel and cost requirements
  • CE consortium would prefer to have a cold box at the ITF and

perform cold testing on a sample of APAs (15-20% feasible) there

  • No decision taken

What else is coming ?

  • Agreed with technical coordination on a set of 3 preliminary

design reviews

  • Mechanical aspects of Cold Electronics (involves cable plant size,

cable connections, cable trays, cryostat penetrations)

  • ASICs and FEMBs
  • All the rest including system aspects
  • The first of these reviews will take place in February, the others

in May/June

  • Charge for the February review available, will be posted on the

Indico page

Documentation for Reviews

  • The documentation for these reviews will be more extensive

than just slides (and possibly designs)

  • Engineering notes will be required (need examples, it’s good we

are not going to be the first group to be reviewed)

  • Technical Coordination is (finally !!!) setting up a repository in

EDMS for drawing / documentation

  • We will be using a combination of EDMS / DocDB, with links from

EDMS into DocDB (not viceversa) when appropriate

  • Standard for engineering notes and for review of engineering

designs under discussion

  • Will probably happen at the time of the final design reviews
