Measuring the length of stretched wires with a avalanche oscillator
Bernard Gottschalk
We measure the length of stretched wire pairs by using them as the delay line pulse shaping element in an avalanche oscillator. The circuitry and method are extremely simple, and i…
Using a 3D printer for 2D beam profile measurements in proton radiotherapy
Ethan W. Cascio, Bernard Gottschalk
We have used an inexpensive 3D printer mounting an inexpensive pre-irradiated silicon diode to measure the 2D dose distribution of a small (approximately 10mm FWHM) proton beam. z…
Rapid measurement of tension in multi-wire arrays using free damped oscillations
Bernard Gottschalk
We explore the possibility of using free (as opposed to driven) oscillations to verify wire tension in large, open-frame multiwire planes. Using finite-element simulation we predic…
Radiotherapy Proton Interactions in Matter
Bernard Gottschalk
A survey of physics useful to proton radiotherapy, centered on stopping, scattering and hard scatters: 1. Introduction 2. The fundamental formula dose = fluence x mass stopping pow…
Global surface temperature trends and the effect of World War II
Bernard Gottschalk
Using parametric analysis (curve fitting) we find a persistent temperature bump, coincident with World War II (WW2), in eight independent time series, four land- and four ocean-bas…
Global surface temperature trends and the effect of World War II: a parametric analysis (long version)
Bernard Gottschalk
We fit 12 independent surface temperature time series (zones of latitude), 6 land- and 6 ocean-based, with a Gaussian (centered around WW2) on a quadratic background. The four pola…
