Nuclear Physics

At MAX-lab, Lund University, Lund, Sweden

In connection with the upgrade of the injector and the construction of MAX III, the nuclear physics tagging facility was upgraded as well. The goal of this upgrade is to increase the injected electron energy to 250 MeV and to slowly extract the electrons from the MAX I ring operated in the stretcher mode. The nuclear physics experimental area was enlarged to house larger detectors systems and to provide longer flight paths. Furthermore a new achromatic beam line has been designed and installed together with the tagging spectrometers formerly used at the Saskatchewan Accelerator Laboratory (SAL). The first stretched beam was delivered in May 2006. Since then the tagging facility and the MAX I stretcher ring has been commissioned in parallel with the commissioning of new experimental equipment . The experimental program is well underway and run reports are issued on the MAX-lab homepage following each beam time period. At present the nuclear physics program have 18 weeks of beam time per year. The available electron energy range is 142 to 200 MeV. The electron beam from the injector, operating at 10 Hz, is about 200 ns wide. In MAX I this beam is stretched over 100 ms resulting in a duty cycle of about 50 per cent. The intensity of the beam has gradually increased and is at present about 30 nA.

The tagged photon facility at MAX-lab is used for photonuclear experiments with a high degree of precision and a series of experiments are taking data. The efforts at the tagged photon facility are pursued within an international collaboration with around fifty members.
