The Superconducting dipole magnet consists of the yoke of the magnet executed from soft magnetic steel and superconducting windings of excitation

Two superconducting windings are executed from the superconducting cable and can miss on 1500 А (1200 kAw) current of excitation everyone The working current provides the field in the gap of the magnet 12 T

The field integral along the beam direction is equal 1 Tm Low values of the field in the RICH area (250 Gs) is reached by the installation of double magnetic shield between the yoke and RICH

IIn order to keep to out schedule for the conn order to keep to out schedule for the consstruction of truction of CBM we want to make some steps towards the Technical CBM we want to make some steps towards the Technical Design ReportsDesign Reports

One intermediate step is to organize an evaluation of the One intermediate step is to organize an evaluation of the detector and magnet concepts As the superconducting detector and magnet concepts As the superconducting dipole magnet is already much advanced we suggest to dipole magnet is already much advanced we suggest to organize an evaluation of the magnet concept by external organize an evaluation of the magnet concept by external experts at the end of 2010experts at the end of 2010

The first step would be that The first step would be that wewe write up a report on our write up a report on our plans for the magnet This report plans for the magnet This report willwill have 20-30 pages have 20-30 pages plus drawings andplus drawings and it it will be sent to the experts some will be sent to the experts some month prior the evaluation in July 2010month prior the evaluation in July 2010

The Superconducting dipole magnet consists of the yoke of the magnet executed from soft magnetic steel and superconducting windings of excitation

Two superconducting windings are executed from the superconducting cable and can miss on 1500 А (1200 kAw) current of excitation everyone The working current provides the field in the gap of the magnet 12 T

The field integral along the beam direction is equal 1 Tm Low values of the field in the RICH area (250 Gs) is reached by the installation of double magnetic shield between the yoke and RICH

IIn order to keep to out schedule for the conn order to keep to out schedule for the consstruction of truction of CBM we want to make some steps towards the Technical CBM we want to make some steps towards the Technical Design ReportsDesign Reports

One intermediate step is to organize an evaluation of the One intermediate step is to organize an evaluation of the detector and magnet concepts As the superconducting detector and magnet concepts As the superconducting dipole magnet is already much advanced we suggest to dipole magnet is already much advanced we suggest to organize an evaluation of the magnet concept by external organize an evaluation of the magnet concept by external experts at the end of 2010experts at the end of 2010

The first step would be that The first step would be that wewe write up a report on our write up a report on our plans for the magnet This report plans for the magnet This report willwill have 20-30 pages have 20-30 pages plus drawings andplus drawings and it it will be sent to the experts some will be sent to the experts some month prior the evaluation in July 2010month prior the evaluation in July 2010

ConclusionConclusion

The engineering design for the magnet with a gap size The engineering design for the magnet with a gap size 13х13х10 m13х13х10 m33 (height width and length) provides a (height width and length) provides a required magnitude of the field inside the gap and good required magnitude of the field inside the gap and good screening of the field within RICHscreening of the field within RICH

The factor of screening of the magnetic field in The factor of screening of the magnetic field in comparison with the variant without screens is close to comparison with the variant without screens is close to 35 times 35 times

The gap of the magnet satisfies the available geometry The gap of the magnet satisfies the available geometry of the STS detector and has no elements which could of the STS detector and has no elements which could interfere with moving the detector in the gap and directly interfere with moving the detector in the gap and directly in front of the magnetin front of the magnet
