Objective during shut-down for AS tanksPreparation of two AS tanks and one waveguide

network Tank with the existing structure (problem: 15

MHz out of frequency – 2 MHz only before beam test

Tank with a new structure

At the end of shut down, decision on which tank to install in CLEX

Main activities for TD24 tank1. Tank with TD24 (existing)

1. Dismounting from CLEX (RP issues) – transport to B169

2. RF measurements3. Brazing of tuning studs to allow for tuning by

pulling + brazing of cooling circuits4. Tuning 5. Baking 6. Assembly7. RF check

TBTS Phase 2.1 T24 Ø45mm

Option 1: Existing waveguide circuit

10

TBTS Phase 2.1 T24 Ø45mm

Missing components

Option 2: New waveguide circuit foreseen for CEA structures

11

TBTS Phase 2.1 T24 Ø45mmSTANDARD DISK

Missing component

Smaller disk diameter, but 80 mm coupler (the same as TD24)

12

TBTS Phase 2.1 T24 Ø45mm (new components)

New cooling tubes

13

Main activities for T24 tank1. Tank with T24 (new / tuned on 17.07)

1. Baking (needed ad-hoc support)2. Procurement of missing components

2 cooling tubes (O1) 3 missing waveguides (O2) The new set of more compact waveguides (for the

future CEA accelerating structure) (O2) Modified tank (for the future CEA accelerating structure)

(O2) Modified support (for the future CEA accelerating

structure) (O2)

Conclusions A lot of work during CLEX shutdown! Aim: to be ready for installation at the end of

February https://edms.cern.ch/document/1108714/1
