Task7 nustar2 design and prototype construction of a radiation resistant magnet

Task7: NUSTAR2 - Design and Prototype Construction of a Radiation-Resistant Magnet

Martin Winkler

Kick-off meeting EU DS "DIRACsecondary-Beams", April 14-15, 2005, GSI, Darmstadt, Germany

  • The Pre-Separator of the Super-FRS

  • Sub-Tasks of NUSTAR2 (Choice)

  • Implementation Plan, Milestones & Deliverables

  • Project Resources and Budget

Task leader of NUSTAR2: Gebhard Moritz, GSI

Martin Winkler, Task7: NUSTAR2 15-4-05


Design parameters and layout of the super frs

Design parameters and layout of the Super-FRS

Design Parameters

High-radiation area

  • Large phase space  large aperture magnets

  • High beam energies + large apertures

  •  high pole tip fields for quadrupols

  •  use superconducting magnets

Martin Winkler, Task7: NUSTAR2 15-4-05


Requirements of magnetic elements of the preseparator

Requirements of Magnetic Elements of the Preseparator

Can the magnets stay superconducting

after the target and beam dumps?

PF2

1,3

Martin Winkler, Task7: NUSTAR2 15-4-05


Beam dump locations in the 1 st stage of the pre separator

Beam dump locations in the 1st stage of the Pre-Separator

Target

Trajectories of primary beams

with different DBr/ Brbeam

Beam Dumps

Light

fragments

The primary beam is always dumped in well-defined positions

outside the magnets !

Exploration of radiation load on magnets behind the high power production target

Exploration of radiation load on magnets behind the high-power production target

Projectile:

1500 MeV/u 238U 1012/s

σx = 1.0 mm

σy = 2.0 mm

σp /p = 0.5%

Energy deposition distribution

(calculated with PHITS)

Target:

Carbon 4 g/cm2

Geometry

Avarage energy depositionon on the coil surface:

<DE>/M= 0.46 mJ/g

(quench limit: 2-3 mJ/g)

Heat load on the cryogenic system

for a 5 ton quadrupole magnet:

Expected FAIR cryogenic power: 20 kW

≈ 2.3 kW

Martin Winkler, Task7: NUSTAR2 15-4-05


Radiation sensitivity of coil materials and insulator

Radiation sensitivity of coil materials and insulator

Behind target and beam dump:Expected heat load ≈ 1 mJ/g

 is equivalent to a dose rate of 1 Gy/s

Assume 4000 h/year operation time  14 MGy accumulated dose

 Ceramic insulation is required

Martin Winkler, Task7: NUSTAR2 15-4-05


Radiation resistant normal conducting magnet

Radiation resistant (normal-conducting) magnet

Magnet Cross Section

Parameter:

B = 1.6 T

I = 600 A

J = 1.5 A/mm2

P = 50 kW

ΔB/B ≈ 2×10-4

ΔR = ±20 cm

Weights (12.5 m, 11°):

Fe: 72 t

Cu: 9.5 t

Coil Cross Section

Conceptual design of a high precision survey and alignment system for high radiation areas of fair

Conceptual design of a high-precision Survey and Alignment System for high-radiation areas of FAIR

After commissioning of the SuperFRS a very high level of radiation is expected.

S&A "as usual" will not be possible due to prohibited or limited access.

No access of human personnel

High demands on accuracy (some 1/10 of mm)

Handling curved beamlines with a length up to 50 m

"RALF" - Remote ALignment on the Fly

Based on Photogrammetry

non-contact

high accuracy

data capture within a shorttime

Automated guided vehicle system

Remotely controlled adjustment of accelerator components

in cooperation with i3mainz

Institute for Spatial Information and Surveying Technology
