| During 2016 proton physics operation at the CERN Large Hadron Collider (LHC), an asymmetry of up to 10% was observed between the luminosities measured by the ATLAS and CMS experiments. As the same bunch pairs collide in both experiments, a difference in luminosities must be of either geometric or instrumental origin. This paper quantifies the impact of the crossing angle on this asymmetry. As the beams cross in different planes in the two experiments, non-round beams are expected to yield an asymmetry due to the crossing angle. Results from crossing angle measurements at both experiments are also shown and the impact on the luminosities is evaluated. | ||

| TUPVA124 | The Beam Lines Design for the CERN Neutrino Platform in the CERN North Area and an Outlook on Their Expected Performance | 2382 |
|
||
| In the framework of the CERN Neutrino Platform project, extensions to the existing SPS North Area H2 and H4 secondary beam lines, able to provide low-energy charged particles in the momentum range of 0.4 to 12 GeV, have been designed. The parameters of these very low energy beam lines, the expected beam composition as seen by the experiments as well as an outlook on their expected performance are summarized in this paper. Results from Monte-Carlo simulations, important for the optimization of the future instrumentation of the beam lines (serving both the purpose of beam tuning and the experiments' needs for particle identification and momentum measurements), are presented. | ||

| THPVA128 | Preliminary Test Setup of the Metu Defocusing Beam Line, an Irradiation Test Facility in Turkey | 4750 |
|
||
|
Funding: Turkish Ministry of Development METU-Defocusing Beam Line (METU-DBL) Project has been started in August 2015 and aims to construct a beam line at Turkish Atomic Energy Authority Sarayköy Nuclear Education and Research Center Proton Accelerator Facility to perform Single Event Effect (SEE) tests for the first time in Turkey. The METU-DBL is 8m-long and has quadrupole magnets to enlarge the beam size and collimators to reduce the flux. When complete the METU-DBL will provide a beam that is suitable according to ESA ESCC No. 25100 Single Event Effects Test Method and Guidelines standard. The METU-DBL beam size is 15.40cm x 21.55cm and the flux will be variable between 105 p/cm2/s and 1010 p/cm2/s. The METU-DBL will serve space, particle, nuclear and medical physics communities starting from 2018 with performing irradiation tests. A preliminary test setup is being constructed towards first tests in March 2017. The beam size will be 6cm x 8cm and the flux will be 1.4x109 p/cm2/s for preliminary test setup. The METU-DBL project construction status for the preliminary test setup is presented in this poster. |
