Absolute Calibration of a Large-diameter Light Source
Autor: Brack, J. T., Cope, R., Dorofeev, A., Gookin, B., Harton, J. L., Petrov, Y., Rovero, A. C.
A method of absolute calibration for large aperture optical systems is presented, using the example of the Pierre Auger Observatory fluorescence detectors. A 2.5 m diameter light source illuminated by an ultra--violet light emitting diode is calibrat

Multi-wavelength Calibration Procedure for the Pierre Auger Observatory Fluorescence Detectors
Autor: Rovero, A. C., Bauleo, P., Brack, J. T., Harton, J. L., Knapik, R.
We present a method to measure the relative spectral response of the Pierre Auger Observatory Fluorescence Detector. The calibration was done at wavelengths of 320, 337, 355, 380 and 405 nm using an end-to-end technique in which the response of all d

Differential cross sections for pi- p and pi+ p elastic scattering were measured at five energies between 19.9 and 43.3 MeV. The use of the CHAOS magnetic spectrometer at TRIUMF, supplemented by a range telescope for muon background suppression, prov

The Crystal Ball ($CB$) collaboration at $BNL$ has recently presented results regarding a study of the $\pi^- A \to \pi^0\pi^0 A^\prime$ reaction on $H, D, C, Al$ and $Cu$, using a nearly 4$\pi$ detector. Similar results, but for the $\pi^+ A \to \pi

A precision measurement of absolute pi+p and pi-p elastic differential cross sections at incident pion laboratory kinetic energies from T_pi= 141.15 to 267.3 MeV is described. Data were obtained detecting the scattered pion and recoil proton in coinc

p+ p+p± on deuterium at Tp+ = 283 MeV
Autor: BONUTTI, FAUSTINO, CAMERINI, Paolo, FRAGIACOMO, ENRICO, RUI, RINALDO, Grion N., Brack J. T., Felawka L., Gibson E. F., Hofman G., Kermani M., Mathie E. L., McFarland S., Meier R., Raywood K., Ottewell D., Sevior M. E., Smith, G. R., Tacik R., Vicente Vacas M.
New experimental results on the p+d p+p-pp and p+d p+p+nn reactions at Tp+ = 283 MeV are presented. In-plane coincidence data were taken with the CHAOS spectrometer using pions from the M11 channel at TRIUMF. Because of the quasi-free nature of the p

We have studied the two reactions 12C(π+,pp) and 12C(π+,ppp) in one experiment, using the CHAOS spectrometer at TRIUMF, at incident pion energies of 200, 240, and 280 MeV. In both cases, we are able to distinguish between reaction mechanisms involv
