Incoming Inspection & Certification

• ES is issued after the approval of the design report

• Part of the design phase because it defines interfaces with other WP

• ES is an CERN internal document only

• Shows the intended design and interfaces of the magnets

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.

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. 1208752

• The corresponding section should be checked by each WPL to ensure the integration of the magnets into ELENA

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 1298078 (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

III Status• Main bending dipole (MBR)

• Approval deadline was 25.11.2013 and should be released soon

• Normal quadrupole (MQR)• Released on 11.11.2013

• 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
