Hasan Padamsee

2. MILAN TTC, FEB 2018 Collaboration Board Meeting
Successful Applications from 3 Institutes to join TTC
FREIA, Upsala University, Sweden
SINAP, China
RIKEN, Japan

3. FREIA, Upsala University
Facility for Research Instrumentation and Accelerator Development
Horizontal Cryostat, Vertical cryostat
Spoke Cavities, ESS Cryomodules

4. Upgrade of the RIKEN Heavy Ion LINAC (SRILAC)
The RILAC is upgrading to provide intense heavy-ion beams for super heavy element (SHE) synthesis challenging the 8th row of the periodic table of elements (A>=119).
The superconducting linac (SRILAC)mconsists of three cryomodules based on ten QWRs made of bulk Nb.
Ten QWRs planned to be tested by the third quarter of FY2018.
Test facility, First QWR tests, > 10 MV/m

5. SINAP

6. SINAP
Three 500MHz SRF cavity systems with total power of 900kW and Vacc =4.5~6MV.
Digital LLRF system.
The system has operated stably for ~10 years since 2008.
Development of a New Type 500MHz Single Cell cavity SRF Module
Larger beam aperture (Ri=120 mm), fluted beam pipe for HOM propagation, lower loss factor
Coaxial type input coupler: capability for higher power and adjustable coupling
1.5GHz Superconducting third harmonic Cavity
Infrastructure for SRF R&D

7. Shanghai Hard X-ray FEL Facility (SCLF)
An XFEL based on an 8GeV CW Linac with 1MHz rep-rate, total length 3.1km, 29m underground
3 FEL undulator beamlines (0.4-25keV), 10 stations, multi- PWs laser
Approved by the Chinese government in 2017
with cost/schedule: ~1.2B Euros, 7 years ( )
R&D: 100M Euros, most for the SRF techniques / infrastructures
The Linac consists of 75, 1.3GHz, 8-cavity cryomodules and 2, 3.9GHz, 8-cavity cryomodules.
Q0 = 2K

8. SINAP Message
SRF technology, especially for CW operation, will be the focus in the following ~10 years in SINAP.
The new design and techniques developed at SINAP will be shared in TTC.
The Chinese manufactures and suppliers for SRF components will be organized and trained during the construction of the SCLF project. They will be the
potential suppliers for future large-scale accelerator construction.
The infrastructure for SRF cavity test and cryomodule integration established at SINAP can be used in TTC community.
