A total absorption spectrometer for energy measurements of high-energy particles

Proposal to Study High Momentum Transfer Phenomena and Search for New States

“…Having a total of five longitudh.d.l sections for each angular cell will allow us to weight unusually high energy deposition, such as result from electromagnetic conversion of some of the energy, if additional energy resolution is necessary_ (9) Also, energy loss out the back of the calorimeter can be corrected for, if necessary, by adding additional counters at the rear of the calorimeter. We plan to at least reach the resolution obtained by Engler et al (10) They found cr = ±9% for E = 25 GeV. We should be able to obtain cr ~ ±6 or 7% at E = 100 GeV.…”

Calorimeters in astro and particle physics

“…They also studied sampling fluctuations and shower containment by changing the thickness of the lead inserts. A similar study for a hadron calorimeter was done by the Karlsruhe group under the leadership of Schopper motivated by the idea of measuring n-p elastic scattering at CERN [8]. With the vision that calorimeters will play a role not only in accelerator experiments but also in experiments on board of space missions, Hofstadter and his collaborators [9] developed large homogeneous NaI (Tl) and CsI total absorption calorimeters.…”

Scaled energy (z) distributions of charged hadrons observed in deep-inelastic muon scattering at 490 GeV from xenon and deuterium targets

“…We have taken the radius of the xenon nucleus for a conservative estimate of the distance the excited state would travel through the nuclei: d = Rxe Then, the probability of this hadronlike excited state interacting in the xenon nucleus would be given by Eq. (38) and would have a value I = 0.87.…”
