Progress on sub-task 1. Double length CLIC PETS

A. Lara, E Rodríguez, L. Sánchez and F. Toral

CIEMAT

03/05/2011


Pets fabrication copper rods

PETS fabrication: copper rods

First copper rod is already at CIEMAT. Dimensional control OK.

Seven copper rods are being machining.

Expected to finish on week 21

SiC firing:

1000ºC /10-5 mbar/ 2 h

Dimensional control of the first copper rod

First copper rod


Pets fabrication couplers and tank

PETS fabrication: couplers and tank

COUPLERS AND TANK DESIGN IS FINISHED

  • Couplers are being machined at DMP, expected to finish on week 22. Brazing details are agreed with the brazing company (Ecor).

  • Mini tank is ordered, expected to be finished on week 24.


Pets testing design of the rf measurements

PETS testing: design of the RF measurements

Before brazing (optional).

After brazing.

COUPLERS MEASURING S11 AND S12

  • Three different rings:

    • Lo (70 mm)

    • Lo +60 º (4.169mm)

    • Lo+120º (8.337mm)

After brazing

PETS testing: design of the RF measurements

Before EBW. Rods only.

Measurement of S11 and S12.

Measurements of the phase shift with antenna held by a digital ruler (accuracy 0.01 mm) .

EIGTH RODS WITH DAMPING MATERIAL

  • After EBW. Rods + couplers.

    • Measurement of S11 and S12.

    • Bead pull measurements (optional).

Before EBW

After EBW

PETS: future steps

  • Activities for the next months:

    • Finishing the bars, couplers and tank machining.

    • Brazing of one set of couplers at Ecor.

    • RF measurements of the copper rods before assembly.

    • Assembly of the rods by EBW at CERN.
