Production Readiness Review for TDIS

Introduction

The HL-LHC project is progressing into construction phase.

The HL-LHC management deems it necessary to set up a series of reviews to assess the readiness for production of the main and most critical equipment in terms of cost, complexity of construction and performance impact.

TDIS

The TDI is the protection system in case of failure of the MKI. The TDI system showed several weak points already during RUN1. Several interventions were carried out during LS1 and YETS 2016-17 but still some issues are affecting its performance. Furthermore, HL-LHC foresees to double the injection stored energy and significantly increase the energy density.

For all the above reasons it has been decided to design a new TDI, the so called TDIS and install it during LS2.

Mandate

The committee is invited to assess for each equipment:

1. Scope of work: is there a clear definition and clear interfaces?

2. Procedures, construction specifications, executive drawings: are all in approved status, verified by due authority, and well documented?

3. Quality Assurance: is it correctly in place (procedures, documentation, check/holding points, etc.)?

4. Components:
   1. Availability and delivery schedule margin
   2. Logistics (flow and storage)


5. Assembly tools
   1. Availability, qualifications

6. Production planning robustness.

For the Review of the TDIS, the review panel is composed of Diego Perini (chair), Michele Modena, Isabel Bejar Alonso, Bertrand Nicquevert and Alessandro Bertarelli (CERN).
