Development of a reference oscillator for synchronization of particle accelerator subsystems

Z izgradnjo novih sinhrotronskih pospeševalnikov četrte generacije se gradijo tudi potrebe po čedalje bolj natančni sinhronizaciji krmiljenja pospeševalnih enot. Za zagotavljanje teh je potrebna časovna sinhronizacija celotne dolžine pospeševalnika z napako, ki pogosto ne sme presegati časa nekaj deset femtosekund. Diplomsko delo predstavlja razvoj novega referenčnega oscilatorja, ki nadgrajuje funkcionalnost obstoječega sistema. Zasnova novega instrumenta temelji na uporabi temperaturno stabiliziranega kristalnega oscilatorja in tehnologiji direktne digitalne sinteze signalov. Z odpravljenimi problemi proizvodnje, dodanimi novimi funkcijami in primerljivim faznim šumom lahko novi instrument konkurira izdelkom vodilnih proizvajalcev v industriji. Potencialno lahko služi tudi kot osnova za razvoj produkta, ki bi bil primeren za prodajo na širšem trgu.With the construction of new fourth-generation synchrotron accelerators the need for increasingly precise beam control and regulation systems is also being built. In order for those to work the entire length of the accelerator has to be synchronised with a timing error often as low as only a few tens of femtoseconds. The thesis describes the development of a new reference oscillator with a goal of extending the functionality of the previous system. The design of the new instrument is based on the use of an oven controlled crystal oscillator and direct digital synthesis to generate required signals. With the production issues fixed and new features added the instrument has also been able to retain good performance. This puts it on par with products from industry\u27s leading manufacturers. The instrument could serve as a basis for further development of products more suited for a wider market
