An intense molecular beam of CO (X(1)Σ(+)) in high vibrational states (v = 17, 18) was produced by a new approach that we call PUMP - PUMP - PERTURB and DUMP. The basic idea is to access high vibrational states of CO e(3)Σ(-) via a two-photon doubly resonant transition that is perturbed by the A(1)Π state. DUMP -ing from this mixed (predominantly triplet) state allows access to high vibrational...

Vacuum pump wear is the most prevalent failure mode of IBA Synthera® automated radiochemistry system. Rebuilding or replacing causes equipment downtime and increases radiation exposure service personnel. We built a dedicated test device to assess new rebuilt pumps prior installation, thus reducing during repairs. The Testbed incorporates microprocessor that actuates pump, valves, pressure senso...

An investigation into the vibration characteristics of a ‘Roots and Claws’ based dry vacuum pump under different operating conditions was conducted. An AutoRegressive (AR)-based condition monitoring algorithm was developed and tested on both a fault-free and a pump with an implanted ceramic bearing with an inner race defect at the High Vacuum (HV) end. The investigation provided some in-depth u...

One of the main elements to foster technological processes in animal husbandry are vacuumpulse pump devices designed support dosing, mixing, transporting, lines for forage preparation and feeding, milking cows, milk processing, as well a large number agriculture. The paper discusses vacuum-pulse pumping device widely used all industries agriculture, feature which is improve technical characteri...

We report the realization of a bright ultrafast type II parametric down-conversion source of twin beams free of any spatiotemporal correlations in a periodically poled KTiOPO4 (PP-KTP) waveguide. From a robust, single-pass setup it emits pulsed two-mode squeezed vacuum states: photon-number entangled pairs of single-mode pulses or, in terms of continuous variables quantum optics, pulsed Einstei...
