rf measurements and tuning of the 1-m-long 750 MHz radio-frequency quadrupole for artwork analysis
نویسندگان
چکیده
The 750 MHz PIXE-RFQ (radio-frequency quadrupole), developed and built at CERN, provides 2 MeV protons over a length of one meter for proton-induced X-ray emission analysis (PIXE) cultural heritage artwork. In this paper, we report low-power rf measurements tuning the PIXE-RFQ, which have been completed mid-2020. Using novel algorithm based on direct response matrix, field frequency could tuned same time in only two steps to satisfying accuracy. Additionally, single modules, quality factors, coupling strength. all cases, very good agreement between measurement design values was observed.

15 صفحه اولA frequency and amplitude scanned quadrupole mass filter for the analysis of high m/z ions.
Quadrupole mass filters (QMFs) are usually not used to analyze high m/z ions, due to the low frequency resonant circuit that is required to drive them. Here we describe a new approach to generating waveforms for QMFs. Instead of scanning the amplitude of a sine wave to measure the m/z spectrum, the frequency of a trapezoidal wave is digitally scanned. A synchronous, narrow-range (<0.2%) amplitu...
متن کاملRF-DNA: Radio-Frequency Certificates of Authenticity
A certificate of authenticity (COA) is an inexpensive physical object that has a random and unique multidimensional structure S which is hard to near-exactly replicate. An inexpensive device should be able to scan object’s physical “fingerprint,” i.e., obtain a set of features in the form of a multidimensional signal x that pseudo-uniquely represents S. For a given “fingerprint” x and without a...
