ze sa na to uz nevyserem...

[balu na home]

musim sa podelit... Na listovici som spominal, ze si nechavam mensie 
projekty, ktore by boli vhodne na bakalarku/diplomovu pracu a snazim sa 
ich v ramci rozbehnutia spoluprace posunut univerzite.

Uz sa vyhovorili asi 6x. Nemame studentov, mame studentov, nemame cas, 
opytaj sa o tri roky. Vypiseme ako temu. Takze uz to dalej nebudem skusat.

Pre ilustraciu, toto je uplne jednoduchy, verim, ze by to zvladol niekto 
aj ako prakticku maturitu. Jakub? :-)


RF power monitor for the HIE-Isolde post accelerator
The HIE-ISOLDE project is a major upgrade of the ISOLDE and REX-ISOLDE 
facilities at CERN. The most significant improvement will come from 
replacing most of the existing REX accelerating structure by a 
superconducting linear accelerator. The design of this new compact SC 
linac is based on independently phased superconducting quarter-wave 
resonators (QWRs). Each of the 32 resonators is powered by a 700 W, 
101.28 MHz, RF power amplifier.
Values of the forward, reflected, antenna and reference power are 
available from the low-level RF system with great precision. However an 
independent redundant RF measurement and monitoring system is necessary 
for safe and robust RF system operation.
Role of the RF power monitor would be to measure RF power of up to 24 
channels, process the data (noise reduction, long integration time RMS 
value, individual sensor calibration, interlock) and publish them to the 
central CERN control system via a standard industrial bus.
Scope of the project (thesis) will be:
- Determine what type of RF detector is the most appropriate for the 
application and design the RF front end
- Define the measurement system architecture
- Design the control interface, using some of the standard industrial
controllers and protocols (e.g. Rabbit with modbus over ethernet
interface)
- Implement the signal processing, calibration and communication
functionality
- Design, produce and test a prototype
- Design a fully automated test and calibration procedure
- Prepare a full production documentation in English language
- Install and test the system in the HIE-Isolde accelerator at CERN
Preferred communication language (including the final thesis) is 
English. Work on the project may involve one or multiple travels to 
Geneva, Switzerland.
