Summary of activities (I)

Contract starting date: 01-June-2012.

Numerical calculations: CST Particle studio

(electrostatic fields in the Faraday cups).

Literature research: ion-induced electronsemission spectra.

Experimental work at ISOLDE:

• HIE Faraday cup test (next slide).

• Photodiode (beam time structure monitoring).

• Beam profile images with MCP (transverse profile).

Summary of activities (II)

HIE Faraday cup (prototype):• Provided by AVS Added Value Industrial Engineering Solutions

S.L. (Spain)

• Installation 20/08/12.• Measurements with beam (ISOLDE): 20/08; 21/08; 03/09;

12/09• Many interesting results at different energies (stable

beam).

Project Status & Future work

Tests with the prototype for the HIE-ISOLDE Faraday cup ongoing (different polarization options, accurate measurements in the whole energy range, collimator-related effects for the electron emission processes,electrons-collector installation).

A HIE Diagnostic box (with Faraday cup and scanning slits) is arriving soon. It will be installed in L20 (REX-ISOLDE). Functionality tests for it are being planned.

Solid state detector for low intensity beams: Si detector workbench mounted at Prevessin Laboratory, some early studies have been initiated following previous work of F. Zocca (BE/BI) et al.

Conclusions

Conceptual design of the beam instruments for HIE-ISOLDE is well advanced, with some prototype equipment already built and tested at REX-ISOLDE.

Challenging specifications for the diagnostic boxes and its instruments due to a very short longitudinal space available are being studied in collaboration with a multidisciplinary team of experts (instrumentation, radiofrequency, operators, mechanical design, etc).

The CATHI ITN program is an excellent opportunity for my postdoctoral studies, and will probably act as a career booster for me, due to the many contacts and hands-on experience that I am already obtaining.
