## Status Overview: SMT

**Silicon**
**Silicon detector (SMT-S & SMT-N)**
**Installed **
**Infrastructure (cooling, air)**
**H-disks ( need 4)**
**4 H disks installed**
**Infrastructure**
**Cooling system hooked up**
**More later under electronics**

## Fiber Tracker Status

**Waveguide Production and QC continue ****at a very small scale;  use less fiber ( $100K ******** $50K)**
**Installation Waveguides**
**South & North: done**
**VLPC cassettes**

- Goal (99):  projection was Feb 26, 2001
-  now mid March, due to AFE testing

- 91 fabricated, 87 characterized, 66 @D0 , 12 more ready for DØ

## Status Overview 

**Central Muons (94 PDT’s)**
**Commissioning continues**
**Triggering on tracks**
**Forward Muon detectors**
**All commissioned, except B layer pixels;**
**C layer pixels to finish ( timing)**
**Gas systems (recircl. & clean)**
**Being installed**

- Installation status

## Status Overview; Electronics

**Electronics**
**Calorimeter**
**Preamp installation/commissioning underway (55k installed: all done, EN & CC power ready, cooling installed, ES going in)**
**BLS status**
**Motherboard: 1250/1200/1020**
**                 ****need/bare/stuffed**
**  ****( no progress:  50/week; should 100/week)**
**Daughter cards 5000/****5000****/4220**
**Daughter card: 300/week should; but none in last few weeks ( ORACLE SUNYSB ??)**
**CC, ECN were cold and filled with liquid; now empty**
**Have 4 out of 12 timing modules ( boards being assembled)**
**Have read out 4500 channels **
**Muon**
**Done**

## Tracking Electronics
Si Interface Card
144 needed
All boards in hand
144-4 tested and ready
Adapter card
Done fabricating
& installed south side

Analog Front End boards
Remake the PCB’s (148)( second set)
Release Feb 19
PCB status clear: remake !!!
Have 10 prototype boards
4 stuffed;  2 being tested
Tests look promising, but have to continue
Latest release date for stuffing March 19
MCM going
At FNAL 2220;  need 2200
Power supplies
Being installed

| HDI with SVX | - | - | in SMT |
| 8’ Low mass cables & clock cables | 720
192H | 757
232H | SMT support cylinder to CC face  |
| Adapter card | 144*4 | 144*4 | Installed on CC face ( 144*2) |
| 19’-30’ High Mass Cable; 3M/80 Conductor & clock cables | 144*4 | 144*4 ( found all)  | ~288 (south) installed |
| Interface card | 144 | 144 | east & west side of CC; going in |
| 25’ High Mass; 3M/50 Conductor | 144*4 | 144*4 ( missing, reorder or spares) | To sequencer;  3* 144 in |

## Fiber tracker readout front end system status

| Description | # need | # ready | Location |
| --- | --- | --- | --- |
| Waveguides from CFT (axial & stereo), CPS, FPS | - | CFT & CPS DONE | From face of CC to platform  |
| VLPC cassettes | 99 | 87 | platform |
| AFE 8  with 8 MCM’s; readout axials & stereo | 136 incr. | 10 proto problem | On VLPC cassttes |
| MCM; multichip module with SIFT & SVX chip | 2200 | 2212 | On AFE xx boards |

- Infrastructure installed

## Status Overview

**Trigger**
**Final hardware arrival is a worry**
**Level1:**
**CFT trigger; digital parts arriving March**
**CAL few towers on March 1 & run;  delivery in March**
**Muon  ~2octants in central & 1 in each end; arriving in March & April **
**L2 VME-Alpha boards still a concern. Looking better: 25 produced; 3 partially working;  6 completely working.  Expect another 2 to rise from dead.**
**Three approaches:**
**Effort in CD continues (THANKS) **
**Another production run. Have parts for 12 boards. **
**New design completely.....**
**L3 board production concern**
**Abandoned high speed SIB design on PCI card with high bandwidth IN and OUT**
**Goal now is to achieve 50 to ~150Hz in April**
**Two critical boards (SIB, VBDi). SIB have boards, VBDi going out **
**Online**
**In use at low rate, not on critical path**

## Summary

**Concerns**
**Installation:  Mechanically complete**
**Electronics delays are THE concern for realistic commissioning with beam**
**Vendor delays, parts availability**
**Outlook**
**“****Detector” will be ready for beam on March 1**
**All detectors will be installed **
**Not completely hooked up**
**Limited data rate in DAQ ~few Hz**
**Will need TIME after start up to complete the detector electronically ( see later)**
