Beams

The information about 9 MV FN Pelletron Tandem Accelerator and list of beams extracted from the tandem are available here.

Experimental facilities available at IFIN-HH:

ROSPHERE Array

ROSPHERE (ROmanian array for SPectroscopy in HEavy ion REactions) is composed by a total of maximum 25 detectors of two types: Compton suppressed HPGe detectors and fast LaBr3(Ce) scintillator detectors. It is a powerful instrument for lifetime measurements using the in-beam Fast Electronic Scintillation Timing (FEST) method or, together with a state of the art plunger device, using the Recoil Distance Doppler Shift (RDDS) method. If the experiment requires high resolution and high efficiency, ROSPHERE can be operated as a full HPGe array.

Scattering chamber

The experimental set-up working on the zero-degree beam-line of the 9MV Tandem Accelerator at IFIN-HH now offers a high accuracy and repeatability of the heavy ions nuclear physics experiments. This is achieved by an automated moving system, placed inside a circular reaction chamber, consisting of four moving arms covering a complete 360 degrees. Each arm can hold one detector and is powered by a stepper motor having the possibility of micro-stepping up to 1/256 if the application requires, with a reduction gear box of 60:1 and a resolver acting as a witness for eventual position corrections. Moreover, the target support, positioned in the center of the chamber, is also assisted by a stepper motor and can rotate over 360 degrees clockwise or counter clockwise. Two identical Delta E – E telescopes have received an upgrade in both the gas automated pressure and constant flow regulation by using a software implemented PID (Proportional-Integral-Derivative) controller.

Target Preparation Laboratory

The laboratory was developed to support the nuclear physics experiments performed mainly at the IFIN-HH 9 MV Tandem Accelerator or at other international research facilities in the frame of scientific collaborations (CERN, IN2P3, TUM, IKP, JINR, etc).

The laboratory provides thin films of various thicknesses from several tens of μg/cm2 to several hundreds of mg/cm2 made from both naturally occurring materials and stable enriched isotopes. Such thin films (called “targets”) are dedicated for different types of nuclear structure experiments: nuclear structure and lifetimes measurements of excited nuclear states using γ-ray spectroscopy techniques (Doppler shift attenuation, plunger, and fast-timing), nuclear structure studies using the activation technique, cross-section measurements of interest for nuclear astrophysical processes, etc.
