Task 12 2 thin films c antoine cea

Task 12.2 Thin Films (C Antoine – CEA)

ALD @ INP Grenoble

  • Progress since May 2013 will be presented at the April WP12 meeting

CEA Saclay

  • Modification of the magnetometer underway

    INP Grenoble

  • ALD deposition set-up delivered

  • CVD deposited NbNsamples have been characterized.

    CERN

  • Sample study ongoing w. Sheffield U. to study biased HIPIMS

    HZB Berlin

  • Quadrupole resonator close to final fabrication (presently BCP at JLAB)

  • Design of a special sample holder for small flat sample underway


Task 12 3 high gradient nc w wuensch cern

Task 12.3 High Gradient NC (W Wuensch – CERN)

Recruitment:

CEA Saclay – Post-doc hired, begins in April.

Lancaster – Two PDRAs hired, began in January

PSI – Post-doc hired, began in November

Upcoming deliverables:

D12.2 Initial progress report M18 – dedicated effort to begin in four months or so.

Technical progress highlights:

PSI has made initial beam-based measurements and evaluated optical components.

Lancaster has tuned crab-cavity.

CEA Saclay has made preliminary particle studio simulations of klystron.

Overall assessment

Lengthy process of finding and hiring means that real momentum on technical work is just beginning. Nonetheless all work plans have been studied in sufficient detail to allow technical work to start.


Task 12 4 hom beam diagnostics r jones uman

Task 12.4: HOM Beam Diagnostics (R Jones – UMAN)

  • Aim: HOM-based beam phase and position diagnostics for the E-XFEL SC cavities(1.3 and 3.9 GHz)

  • Experimental work:

    • HOM Measurements at FLASH to study stability of signals, correlation to detuning(1.3 GHz cavities)

    • Design of electronics for 1.3 and 3.9 GHz electronics for the E-XFEL on going
