PMG AgendaAugust 3, 2000

• Overview (Weerts)
• Detector status
• Reportable milestones
• Summary
• Silicon (Demarteau)
• Forward Muon (Denisov)
• Installation (Kotcher)
• The next few months (Weerts)

2
Status Overview

• Silicon
• Marcel will give details
• Production of components looking better
• Micron is producing, the end is in sight
• oversight at Promex has improved yield
• Detector looking good
• Dead/noisy channels reasonable
• Low mass cable rate some concern at vendor
• Production rate has dropped, being monitored
  carefully but first half is done
• Fermilab (Jones group) doing excellent job in
  completing cables
• 10 readout test
• Continuous struggle, but are reading out
• F disk will be next

3
Fiber Tracker Status

• Hookup of clear waveguides
• Installation to start end of August ( platform
  move completed)
• Waveguide Production and QC are going well

60 complete
4
Fiber Tracker Status

• VLPC Cassettes
• 36 done
• Sub-component assembly
• 80-98 complete

5
Status Overview

• Forward Preshower
• Both detectors installed
• ICD
• North South Installed
• Luminosity monitor
• North South Installed

6
Status Overview

• Central Muons
• Commissioning continues
• Forward Muon detectors
• Trig Pixels (48 octants)
• All octants assembled tested starting to move
  to DAB
• First A layer plane installed in detector
• Pixel VME crate readout through DAQ
• MDTs (48 octants)
• A layer octants installed
• Readout through DAQ tomorrow
• B octants 8 assembled completion late Aug
• C octants done testing
• Gas systems
• Engineering design manpower . being solved

More from Denisov
7
Status Overview

• Trigger DAQ
• Progressing, no schedule concerns
• Online
• No schedule concerns, not on critical path
• Preparing for CFT waveguide installation
  checkout pushing the DAQ system need full time
  shifters
• Multiple run functionality going
• Solenoid and beam pipe
• Beam pipe installed within D0

8
Status Overview Electronics

• Electronics
• Calorimeter
• 5000 preamps installed on detector (of 55k)
• 100 pre-production BLS boards in hand
• ECS re-cabled
• To allow detector move this week
• Muon
• PDT electronics - done
• Scintillator
• Front end
• Have enough in hand, complete early Sept
• Readout card - done
• MDT - done
• Readout electronics
• Readout 100
• Fanout 15 complete early Nov, enough in hand
  for commissioning

9
Status Overview Electronics

• Tracking Electronics
• Si Interface Card
• Bids are back visiting vendor
• Agreed on final changes to address crosstalk
  issues
• 2 boards immediately on fast turnaround
• 15 boards by end Aug
• Cabling/infrastructure work underway
• Analog Front End boards
• Delayed to mid-Aug (vendor)
• MCM yields improving
• 44 good out of 50
• Unlikely that we need to order additional SVX
  from UTMC bank to cover yields
• Adapter card
• Sept 1 34 pre-production cards

10
Installation

• Installation
• Lots of activity in DAB
• Muons, Fiber tracker, CPS, Calorimeter,Platform
  moving, detector closed ( looks like detector)
• Installation is taking over the upgrade, the
  hall, the experiment, absorbing most manpower and
  Kotcher will talk about it

11
Summary

• Concerns
• There is obvious progress in DØ. Seems clear
  after my absence (is that a sign ? )
• Silicon concerns continue, but shifting from
  production to readout and preparing for receipt
  of Si in DAB
• Electronics delays are a concern for
  commissioning
• Getting the DAB infrastructure in place
• Holding the Nov 1 wall-down date and therefore
  March 2001
• More about that later..

12
The next few months part 1
The DØ schedule Up to November 1 DØ
Assembles, installs commissions until Nov 1,
no access to collision hall, no impact on BD (
have lum. monitoring in and will try to install
SMT radiation monitoring) BD brings up complex,
establish 36x36 operations with collsions,
measure losses Nov 1 thru Feb 28, 01 shutdown
of Tevatron DØ continues to assemble, rolls in
and commissions complete detector.
13
The next few months part 2
Concerns Further problems in
Tevatron Scenario I CDF (no Si) rolls in in
August ( or not), machine starts up with no
collisions until ????. No collisions by Nov 1
? pressure to delay Nov 1 shutdown, because we
desire stable conditions to operate silicon
detectors into beam. DØ currently Nov 1
needs to be fixed. If it slips then March
readiness slips by same amount. Scenario II
things go so wrong that we keep the March 1
date, but redefine what a Run II detector is.
Example no silicon. This decision is made late,
after we have installed siliconnot good. DØ
if this is a conceivable option, we need to know
by Sept 15, 2000 to delay silicon
installation Other scenarios ?? We can only
conceive of one scenario our default
