Digital techniques for real-time pulse shaping in radiation measurements

Recursive algorithms for real-time digital pulse shaping in pulse height measurements have been developed. The differentiated signal from the preamplifier (exponential pulse) is amplified and then digitized . Digital data are deconvolved so that the response of the high-pass network is eliminated. The deconvolved pulse is processed by a time-invariant digital filter which allows trapezoidal/ tr...

Pulse Shape Discrimination Techniques based on Cross-correlation and Principal Component Analysis

Two Pulse Shape Discrimination (PSD) techniques are proposed based on Cross Correlation (CC) and Principal Component Analysis (PCA). In CC-based PSD, two schemes are proposed to discriminate between different decay scintillation pulses. The first CC-based scheme is applied to digitized scintillation pulses in time-domain with different numbers of samples ranging from the last two samples up to ...

Electron-nuclear recoil discrimination by pulse shape analysis

In the framework of the " ULTIMA " project, we use ultra cold superfluid 3 He bolometers for the direct detection of single particle events, aimed for a future use as a dark matter detector. One parameter of the pulse shape observed after such an event is the thermalization time constant τ b. Until now it was believed that this parameter only depends on geometrical factors and superfluid 3 He p...

Continuous variable entanglement by radiation pressure

We show that the radiation pressure of an intense optical field impinging on a perfectly reflecting vibrating mirror is able to entangle in a robust way the first two optical sideband modes. Under appropriate conditions, the generated entangled state is of EPR type [A. Einstein, et al., Phys. Rev. 47, 777 (1935)]. PACS numbers: 42.50.Vk, 03.65.Ud, 03.67.-a
