Philip Schwarz TE-MSC-MNC 5 II Contents Chapter 1: Introduction The introduction contains general information about the ELENA project and the designation for the magnet Further the number of elements and the basic cooling principle are shown This chapter is intended as a general overview for the contents of the document ParameterValueRemark TypeDipole CoolingWater-cooled Drawing codeAD_MBHEK Design and equipment codePXMBHEKCWP Number86 (ring) + 1 (B-Train) + 1 (spare) Example: Main bending magnet (MBR)

Philip Schwarz TE-MSC-MNC 6 II Contents (continuation) Chapter 2: Magnet design This chapter depicts the parameters resulting from the mechanical and the electromagnetic design. The individual components yoke, coil, support and alignment are described. Main performance relevant parameters of magnet are mentioned throughout the subchapters, i.e. information about the required power converter, the required cabling, the weight and dimensions, etc.

Philip Schwarz TE-MSC-MNC 7 II Contents (continuation) Chapter 3: Interfaces of WP 2.2 to other work packages This chapter defines the interfaces between the magnets and other work packages The responsibilities and names of the work packages are according to the management document EDMS no The corresponding section should be checked by each WPL to ensure the integration of the magnets into ELENA

Philip Schwarz TE-MSC-MNC 8 II Contents (continuation) Chapter 4: Safety Aspects This chapter shows all the different security aspects to be considered when operating and handling the magnet: Electricity risks: IP2X, Grounding according to EDMS (protection of equipment only). Magnetic field risks: Magnetic fields below 1 T. Water risk: Spraying of water to other equipment cannot be excluded. Overheating and fire risks: thermo-switches, flow-switches (water cooling only), all materials conforming with IS41. Radiation hazards: at least 1 MGy radiation resistant

Philip Schwarz TE-MSC-MNC 9 III Status Main bending dipole (MBR) Approval deadline was and should be released soon Normal quadrupole (MQR) Released on Skew quadrupole (MQS) Some minor comments open from approval Sextupole (MXR) Mechanical design open; design report not approved yet, should be sent out for engineering check until the end of the year Corrector (MCR) Electromagnetic and mechanical design to be re-visited after review Transfer line dipole (MBL) Some minor comments to be implemented after the engineering check
