    Creating Coherent Light from UV LEDs and Pinhole Aperture

    I've read that using a pinhole aperture and a wavelength filter can turn a "white" incoherent light source like a light bulb into a temporally and spatially coherent light source (albeit at low efficiency). Can a temporally and spatially coherent light source be made with a monoenergetic (or...

    Charge-Sensitivity in Preamplifier

    Thank you! By can you explain to me why? I figured it was charge sensitive, but I'm having a hard time grasping why.

    Charge-Sensitivity in Preamplifier

    How I tell if a preamplifier is charge sensitive? I have data taken from a preamplifier that is fed a pulse from a voltage pulser that is fed through a current generator. As the pulse voltage was increased the preamp output voltage increased linearly. As the pulse width was increase the preamp...

    Level After Decay of Radioactive Isotope

    Hello! So I have an issue with determining the probability of a daughter isotope's nucleus being on a certain level after decay from an unstable parent isotope's nucleus on another level. For example: I have a Co-60 nucleus and it decays to a Ni-60 nucleus by B- emission. If the parent Co-60...
