Abstract
The implementation of radio‐frequency (RF) techniques at the ISIS muon facility is discussed and the merits of working at a pulsed source considered, including the low RF duty factor, the very low background and the inherently time differential method of data collection. Emphasis is placed on the application of pulsed RF methods to the muon spin resonance experiment and the paper explores the use of a 90\circ pulse to completely remove the frequency limitations imposed on conventional transverse μSR experiments by the finite muon pulse width. The implementation of the 90\circ pulse technique is discussed and demonstrated by observing precession frequencies in quartz at approximately 20 MHz.
