# Presentation: 345071

**Primary Requirement:** Assure that appropriate diagnostic systems are ready for:
- Each phase of commissioning through CD-4 (10^13 on target)
- Performance increases after CD-4 (10^14 on target in a couple of years)
**Primary challenge:** Staffing plan for the ORNL Diagnostics group does not support deployment of all Ring/Transfer line diagnostic systems before commissioning.

**Response**
- The initial functionality (i.e. 6 Hz data acquisition, reduced set of process variables, simplified timing, etc) has been defined.
- Systems have been prioritized to allow phased deployment
- Assumptions:
- Initial commissioning goals can be met with a reduced suite of diagnostics
- BNL and LANL will deliver quality systems on schedule
- ORNL Diagnostics team (reaching 9 permanent staff in ’04) is supplemented by temporary staff
- Primary Constraint: All labs must execute the plan within current budget

##  From the Dec 2000 DAC Report:

**Committee Observation** - At some point in the project, budget, manpower, and/or schedule resource competition will force difficult priorities to be set or perhaps even cuts to be made in beam diagnostics systems.  It is appropriate at this stage of the project to plan for a full suite of diagnostics and valuable to carry on R&D on potentially valuable instruments such as laser wires and IPMs.
**Suggestion** - Assure that diagnostics ‘requirements’ remain differentiated from ‘desires’ and that the fundamental beam performance and machine protection issues are appropriately addressed by the requirements.  This will permit a path to clear decision making if/when push comes to shove.

## Key Milestones

| milestone | date |
| --- | --- |
| Front End | 10/29/2002 |
| DTL1/D-Plate | 8/12/2003 |
| DTL 1-3 | 3/29/2004 |
| DTL 4 - CCL | 8/2/2004 |
| SCL | 2/11/2005 |
| HEBT/Ring | 6/20/2005 |
| RTBT | 1/12/2006 |

- Diagnostics must be ready to support each stage of beam commissioning

## Device Installation (baseline)

**Example of a Device:** One wire scanner system consisting of actuator w/vacuum feedthroughs, cabling, analog chassis, motor drive chassis, PC chassis, MPS interface, collision avoidance interface

## Device Installation

- Installation effort scales with Field Replaceable Units (FRU)
- These units are individually acceptance tested and installed
- Repairs: replace FRU with spare
- Example FRUs:
- rack mount computer with data acquisition boards
- Wire scanner assembly on vacuum flange
- Integration effort scales with Signals
- Signals/device - a rough metric for complexity that assumes minimum coupling
-  Example of scaling to effort: simple integration tests require about one hour per signal

## Device Installation, Field Replaceable Unit Installation, Signal Integration (baseline)

## Rate of Installation, Integration, and Maintenance (baseline)

- Rate in units of signals/week (take complexity into account)
- Maintenance assumptions
- Annual maintenance is typically 10% of total system cost
- Planned installation and integration is 15% of total system cost

## Rate of Installation, Integration, and Maintenance (Phased Deployment)

- Same as previous slide, but flatten peak by stretching integration time.
- All systems ready for beam by CD4, but several are not available during commissioning
- Supports Mike Plum’s commissioning and operations plan
- No float; high schedule risk.

## Resource Plot (phased deployment)

- Includes existing installation plan plus support activities
- Supports commissioning and operations as described by Mike Plum

## DOE Recommendation

**Action Description: **Consider ways to supplement the staffing of the SNS diagnostics group to better support installation and commissioning.
**Status: **Closed
**Response to Action: **ASD has authorized three Russian visitors of various durations for Diagnostics and also instructed other ASD groups to support diagnostics. The Diagnostics Group is receiving substantial support from the Mechanical Group in the design shop and vacuum task areas.

**Ring Systems prioritized**

- Phased Deployment Plan:
- Red: Plan to deploy for commissioning, but with minimal features
- Black: Install, but defer full deployment until after commissioning

**General consensus of DAC, AP**

- With current resources, only top 3 systems will be deployed for HEBT, Ring, and RTBT commissioning
