   Nyckelord :Physics; Heavy Ion Induced Desorption; Ultra High Vacuum; NEG Coating; Heavy Ion Accelerators; Test Particle Monte-Carlo; Gas Flow; Throughput; Laser Refractometry; Metrology; Fysik;

   Sammanfattning : During operation of heavy ion accelerators a significant pressure rise has been observed when the intensity of the high energy beam was increased. The cause for this pressure rise is ion induced desorption, which is the result when beam ions collide with residual gas molecules in the accelerator, whereby they undergo charge exchange. LÄS MER

4. 3. Growth and decline in rural Sweden : geographical distribution of employment and population 1960–2010
