1. 1. Frequency Map Analysis of the MAX IV Storage Rings

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Johan Lundquist; [2019]
   Keywords : Accelerator; MAX IV; Tune; Diagnostics; Turn by turn; Frequency map; Chromaticity; Beta function; BPM; Synchrotron; Physics and Astronomy;

   Abstract : As a beam of particles moves through a storage ring each particle will perform transverse oscillations as a result of the focusing magnetic fields it encounters. The amount of transverse oscillations performed in a single revolution of the ring is known as the particle's betatron tune. READ MORE

3. 2. High-chromaticity Optics for the MAX IV 3 GeV Storage Ring

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Teresia Olsson; [2013]
   Keywords : electron accelerator; MAX IV; storage ring; beam dynamics; chromaticity; Physics and Astronomy; Technology and Engineering;

   Abstract : The MAX IV facility is a 3rd generation state-of-the-art synchrotron light source currently under construction in Lund, Sweden. The MAX IV 3 GeV storage ring has a large negative natural chromaticity, which has to be corrected to positive values to prevent head-tail instabilities. READ MORE

4. 3. Shadow detection for improved object tracking in surveillance cameras

   University essay from Lunds universitet/Matematik LTH

   Author : Katarina Berg; Jonna Hellström Håkansson; [2013]
   Keywords : Technology and Engineering;

   Abstract : Object tracking algorithms and motion triggered alarms are often dis- turbed by shadows. It is challenging to separate between moving objects and shadows since they have similar movement patterns and image prop- erties. In this thesis, three different approaches to detect shadows are developed and evaluated. READ MORE
