Background

PhD at university of Heidelberg/MPIK (DE)

Project : Electron cooler for Cryogenic Storage Ring (CSR) at MPIK (Heidelberg).

Tasks: • Numerical simulations of electron optics;• Experiments on dense ultra-low energy electron beams;• Mechanical and thermal design, applied cryogenics.

Achievements: • Simulation based specs for magnets;• LNeon closed cycle cryogenic cooling system designed and built;• Prototype HTS superconducting magnet designed and built;• Cooling system and magnets put in test operation.


Activity at CERN

WP8: Radioactive Ion Beam Quality Improvement / ER3:Charge breeder design study

Simulations of high current space charge limited electron beam for HIE-EBIS;

Simulation based design of High Energy Current and Compression (HEC2) electron gun, drift tubes, High Power Collector (HPC) and spec for the magnetic system;

General design concept of the HIE-EBIS;


Project status and achievements after 3 months

Active knowledge transfer:

Visited best performing relevant EBIT/S groups at MPIK, BNL, MSU/NSCL.

Preliminary agreement on collaborative construction of the HEC2 gun with BNL, getting approval at CERN. If approved and funded the gun can be built and tested within the 2 years WP*.

HIE-EBIS wide board workshop** with attendance of 28 on 16-17.10 to discuss the options and get feedback from CERN and external experts

* Goes beyond WP **CATHI sponsored

Outlook and options

The gun HEC2 will be built and experimentally tested at BNL EBTS facility *

HPC and drift tube structure will be designed adopting BNL/ANL scheme to a detailed phase.

Simulation based specs for the magnet and general design concept of the HIE-EBIS will be elaborated

The HEC2 gun will be modeled and designed

HPC and the drift tube structure will be simulated and designed to the first order.

Simulation based specs for the magnet and general design concept of the HIE-EBIS will be elaborated

VS.


Experience in the project

Trainings and personal development

Learning from best performing EBIT/S groups

Intensive training in COMSOL to utilize multiphysics approach in design (Sep 12)

CERN Accelerator School to extend accelerator physics background (Oct 12)


Conclusion

Keeping up with the plan

Trainings: according to the CDP (COMSOL taken, CAS – registered Oct, French - registered Oct)

Milestones: M41 first one to be delivered by mid October (HIE-EBIS WS)

Deliverables: according to the plan

Meetings (CERN TE-MSC, TE-VSC, MPIK), secondments (BNL, MSU/NSCL) : according to the CDP.

Conferences: EMIS 2012 registered according to the CDP.

Networking/collaboration: if approved the HEC2 collaboration with BNL profits both the ER3 and the HIE-EBIS project by more effective use of resources, saving time, working with and learning from the best specialists using the unique facility.
