## Outline

**Recent Developments**
**Response to Recommendations**
**Issues**
**Summary**

## US CMS - DOE, NSF Profile

**Strategy is to saturate budget authority for the first 7 fiscal years. We have modified I&C planning to match the CERN and CMS schedule – e.g. FY05. **

## EAC Now Computed with ACWP

**For FY96,97,98,99,00 we use ACWP on tasks completed more than 1 year ago = Closed and Completed (CLAC) tasks to compute EAC.**

## Closed Tasks at UMinn for HCAL

**Each SOW Contract was informed of closing tasks. One year after the end of a completed task is allowed for invoicing. Invoices (ACWP) tracked at the lowest WBS level were used in comparing to estimated costs = BCWS **

## EAC vs. BAC at L2

**US CMS starting at  the end of FY01 uses EAC computed using CLAC tasks. The EAC for completed and closed tasks is the actual cost. For all other tasks it is the estimated cost.**

## US CMS - Financial Overview 

-  **TPC = Constant                   167.25 **
**                                                 ****(AYM$)**
** ****EAC                                       136.48**
** ****Contingency = TPC - EAC    30.77**
** ****ETC = EAC - BCWP             51.18**
** ****BCWP/EAC                           62 %**
** ****Contingency/ETC                  60 %**

**There is a fixed total cost. The Project is 62 % complete and retains 60% contingency on the estimated cost to complete. **

## Contingency History

**The use of contingency to date has been ~ 20% of the work done. This to compare to 60 % of the ETC.**

## Tracking and Reporting

**No trends are evident after initial rapid spending and early lag in invoicing. There are 40 months of reporting since base-lining.**

## Contingency Use

**The earned contingency allows for ME1/1 scope increase to be implemented early in FY02. QP (HF) fiber scope in HCAL is done. DAQ/ECAL is ~ a wash. We expect 0.25 M$ loan repayment from SWC to PO in FY02.**

## Progress Toward Completion

**US CMS plans to go ahead at full speed in the production, delivery, installation and commissioning (I&C) of deliverables. “Slice” tests in SX5 will be used for M&O.**

## CMS ML1 Adopted - CR

**For US CMS, there is no basic schedule issue. All L2 go as fast as possible to the SX5 assembly area. Any further delay in UX5 costs ~ 5 M$/yr.**

## EMU Developments

**Use alignment staging to cover increased costs of CSC production in MP9.**
**The schedule requires a decision on ME1/1 scope increase. Use contingency earned in using actual costs.**
**PRR at PNPI and IHEP. CSC production is in full swing.**
**FAST sites have chambers. Throughput by the end of the CY, pending ALCT.**

## ME1/1 Options

**Scope increase to cover default on electronics is needed for a “working detector”. Option B favored by CMS - recoverable.**

## HCAL Developments

**EDR – HF mechanics**
**PRR – HF PMT and QP fiber**
**PRR – HCAL RBX for HB, HE**
**QIE proto tested, HPD tested. **
**QP fibers (1.48 M$), HF PMT (0.53 M$) and HPD (1.52 M$) will all be brought under contract within 1 month. Earned contingency used for scope increase in QP.**
**Longitudinal segmentation in HB/HE and HF also used to earn contingency – descope.**

## QIE Schedule

## HPD – Crosstalk Test

**New prototype from DEP. Error in connecting bias voltage to pixels – but repaired by surgery and AR coating evaluated. Crosstalk is within spec if error corrected. Raddam test with HV on.**

## ECAL Purchases

**ADC must be purchased to maintain EB schedule.**
**ETHZ has funding profile ******** cash flow problems.**
**US CMS made an unsecured loan of 1.76 M$ to ECAL to purchase APD. This is covered by a descope (recoverable) of DAQ purchases in FY04 and FY05.**

## Other L2 Progress

**Trigger TDR. DAQ TDR delayed 1 year. Modular DAQ for staging put in place.**
**FPIX – delays in ROC. DMILL -> 0.25 um IBM in train.**
**SiTrkr – delays in parts supplies from CMS. Major detector and hybrid contracts have been placed.**
**PO unchanged**
**CP essentially completed.**

## Lehman Recommendations

** ****There has been an effort to make a complete I&C plan for services (Loveless) and for cable runs (Korytov). Presentation at this meeting.**

## Recommendations - II

**The HPD has close scrutiny. Radiation tests with HV on are complete – order placed. QIE back for evaluation – looks good. We have a commitment for a US CMS I&C physicist and we will build on that. **

## Recommendations - III

**The US CMS PO has made a presentation for base resources in FY02 with DOE and NSF on Sept. 20. TRIDAS was an integral part of that discussion.**

## Recommendations - IV

**The FPPA is being explored as rapidly and as intensively as possible. External supply of the bias ******** noise ~ expected. However, CMS wants to evaluate the entire ECAL electronics effort. Peter Sharp oversees the CERN effort. ADC cash flow problem addressed by US CMS.**

## Recommendations - V

**Bruno Gobbi and Dick Lander have abandoned hiring a postdoc and are in train with finding and hiring a technical specialist. Contingency will be applied to maintain the schedule.**

## Recommendations - VI

**The delivery is in the hands of others. The UCSB production line can be set up at ~ no cost using engineering base resources at UCSB in trade for capital equipment ( automation  and wire bonder ). As Run IIb planning becomes more concrete, the use of the additional line will become more important.**

## P.O. Recommendations

**The P.O. revises the cost estimate for each subsystem on a monthly basis.**

## P.O. - II

## P.O. - III

## Issues and Plans

**Continue to “close the door” on ACWP, using a “rolling closeout” of completed tasks - CLAC.**
** ****Solve the ME1/1 problem asap.**
**Prepare for the move to CERN – US CMS CERN PO, and begin I&C.**
**Refine the I&C plan and the transition to M&O. Press to start M&O in FY02 and baseline the Research Program.**

## CMS Costs

**CMS Costs**

**Shortfall of ~15% addressed by CMS with new groups ( Iran, Brazil, Mexico, Ireland, New Zealand, Serbia, US - NP ?), staging (EE ?), and possible additional funds (not from US HEP).**

## Future Calls on Contingency?

**Tracker ~ OK**
**HCAL  ~ OK**
**EMU - Defer alignment so that MP9 is covered. Expect ~ 2 M$ for ME1/1 on chamber electronics and cables ( ME4/1 still pending ).**

## Summary

**US CMS is on schedule and on budget**
**Contingency is being earned by good cost experience and staging/descoping in anticipation of and planning for new needs.**
**Technical progress has been good recently (next talk).**
**Planning for I&C -> M&O will continue (third talk).**
