2. Pakistani colleagues in the magnet group
Sumera Yamin (physicist) and Khalid Mansoor Hassan (electrical engineer) from the National Centre for Physics in Islamabad joined CERN for 12 months, from Feb to Jan
They spent most of the time in the TE-MSC-MNC section (Magnet Normal Conducting), with about 55 colleagues (20 staff members and many fellows, associates and students ).

4. Three solenoids for the ALPHA experiment
Khalid and Sumera performed the magnetic design of three solenoids for the ALPHA experiment at CERN. They also participated in the mechanical design, manufacture and certification of the magnets in our workshops.
The three solenoids are now installed as part of the ALPHA-2 experiment, to transfer particles and antiparticles between various parts of the setup.

5. A 3d magnetic model of the frame.
The NORMA-Frame
After an original idea of Davide Tommasini, Sumera has designed, followed the manufacture of and validated a new concept of permeameter.
This instrument is capable of measuring the BH characteristics of steel sheets following the history of the excitation, to characterize hysteresis cycles as a function of the initial magnetization status of the material.

6. The laminated version of the Q74.
The Q74 magnet
The main magnets in the East Experimental Area may be upgraded from dc to pulsed operation, with a × 10 saving on running costs. The yokes of the magnets need to be re-designed and re-manufactured for this energy saving configuration.
Khalid followed a pilot initiative for one of these magnets, the Q74, producing an updated magnetic design, compatible with the new mechanical assembly.
The manufacture of four quadrants (a complete magnet yoke) in Pakistan with punched laminations of electrical steel provided by CERN is being discussed with HMC-3, Taxila. A proposal for the stacking tooling and procedure is under review.

7. The SESAME building near Amman, Jordan.
Synchrotron-light for Experimental Science & Applications in the Middle East
It is a cooperative venture set up on the model of CERN. The current members are: Bahrain, Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, Palestinian Authority, Turkey.
The electron beam energy is 2.5 GeV, for a nominal emittance of 26.0 nm∙rad. The storage ring is m long, with 16 straight sections, resulting in up to 28 beam lines. Start of the commissioning is expected by end of 2015.

8. CERN and the SESAME magnets
An agreement (FP7 CESSAMag) is being signed between CERN and the European Commission, in the framework of cooperation policies with the Mediterranean region. The goal of this CERN-EC project is to support SESAME by providing the storage ring magnetic system and appropriate training to its staff.
This CERN-EC project is complemented by a CERN-SESAME umbrella agreement, signed by the two General Directors.

9. SESAME sextupoles and Pakistan
We are exploring the possibility of manufacturing 32 sextupoles / correctors (plus spares) electromagnets in Pakistan (HMC-3, Taxila) for SESAME.
The responsibility for the quality of these magnets will be on CERN.
Some of the components will be provided directly by CERN (for example, punched steel laminations, insulated hollow conductor and enamelled conductor).
We are organizing the production of a first pre-series magnet in our workshop in the coming months. Colleagues from Pakistan will visit in June. We shall receive within 10 days a budgetary envelope for this activity.
