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
