1. Module roadmap to end of 2017
The coffee drinkers

2. Work to be done until end of year
New DB Module layout work
New K Module layout work
Heat to air study
Thermal tests
Sara’s breakdown compensation method
Documentation of current T0#2 and T1 design changes with respect to CDR design T0#1 as CLIC note

Rejected ‘rigid’ solution
All are feasible in principle
Main considerations for comparison coming from lifecycle considerations:
Transportation
Effort (cost/time) of installation in the tunnel
RF phasing
Cost of actuators/controls
T1-T2 compatibility
Adjustable in the tunnel

4. New DB Module layout work
Finish design of “2 DoF support box”
Manufacture and test “2 DoF support box”
Continue exploring and conclude on designs for common RF girder
Implementation into real machine: wire, magnet support, SAS interface, virtual articulation point?
Manufacture common RF girder?
2m option, start discussing how the “support structure” (girder + actuators) should look like: wire implementation, in tunnel alignment options
Generic open questions: cooling and vacuum design, vacuum valves (sectorization every 2 m? for e.g. module interconnection), structure interconnection,
Validate or discard:
Klystron lattice (-> important for common RF girder and “1m module”)
“1m module” itself useful?
Explore further importance and technical implementation of RF phasing
Write CLIC note documenting thinking/decision taking process (can be the first part of final deliverable in 2018)

5. New K Module layout work
Options from DB version narrow down
Validate and conclude
Longitudinal positioning implementation
Implementation of auxiliary systems
Implementation of survey system

6. Heat to air study CFD simulations
Upgrade hard- and software of lab for better controlled test:
Flow meter and temp sensor for climatisation system
Flow controller (software)
Installation of load heaters and measure the “entire system” (SAS+RF loads)
Simple insulation extended to RF loads and decide if useful
-> if useful then properly design insulation
Study of local micro climatisation station together with C&V
Study potential insulation for entire module (lid or cover)

7. Thermal tests
Cooling system compensation of thermal effects in AS (based on flow OR temp) continuation of Sara’s work
Thermal-structural FEM
Survey campaign static
Temp and vacuum ?
Transients
Chocke mode flange study

8. Sara’s breakdown compensation method
Assess the relevance of this w.r.t. the current breakdown recovery method
Assess feasibility of having proportional valves for each AS
Question overall cooling layout for module (e.g. loads in series of AS)
