The advantages of &#039;&#039;pulsed&#039;&#039; muons are (1) that there is in principle no limit on how many muons can be stopped simultaneously in a sample; and (2) that irradiation with (&#039;&#039;e.g.&#039;&#039;) RF power for muon spin &#039;&#039;resonance&#039;&#039; experiments is vastly more efficient when applied to many muons at once.  The primary disadvantages are (1) poor time resolution due to finite pulse width defining &quot;&amp;lt;math&amp;gt;t=0&amp;lt;/math&amp;gt;&quot;; (2) the need to break up detectors into many small segments to avoid &quot;pile-up&quot; distortions.  &lt;/div&gt;&lt;/td&gt;
