At the occasion of the SOFT 2016 Conference Dr. Radomír Pánek presented future plans for the COMPASS-U at the SOFT conference.
Dr. Pánek presented a project of a major upgrade of the COMPASS infrastructure. The corresponding proposal has been submitted for evaluation in response to the national Call for proposals of new research infrastructures in the Czech Republic which will be funded from European Structural and Investment Funds.
COMPASS-U will be a high magnetic field device with relevant plasma geometries is missing in the European fusion programme (and worldwide after the shut-down of Alcator C-MOD). The purpose of the project is to enlarge the COMPASS operational space, improve its performance and address some of the key gaps in the Plasma Exhaust Physics (PEX). The upgrade will keep the advantage of mid-size devices with their flexibility for scalings towards ITER and DEMO.
The start of operation is planned at the end of 2021. A broad participation of the European and international partners in exploitation is expected.
The COMPASS-U design offers a wide, and in many ways unique, parameter range and a high flexibility of operation:
- R = 0,84 m
- a = 0,28 m
- B T = 5 T
- I p = 2 MA
- P NBI = 4-5 MW
- P ECRH = 4 MW (170 GHZ)
- Triangularity up to 0,6
- Plasma volume ~ 2 m 3
- Discharge length 1-5 s
- <T e> ~ <T i> ~ 2,5 keV at high density
- n G ~ 8 x 10 20 m -3
- Metallic first wall device
- High-temperature operation (~ 300°C)
