A Blast Wave Diagnostic for the Petawatt Laser System

Blast-wave Snapshots from Rhic

I present fits with the so-called blast-wave model to single-particle spectra and HBT correlations from Au+Au collisions at a CMS energy of 130 AGeV. There is only little choice of freeze-out temperature and transverse flow velocity for which the model fits both the identified spectra and the correlation radii just well enough not to be excluded. The observed steep M⊥ dependence of Rside leads ...

Numerical Investigation of Circular Plates Deformation under Air Blast Wave

In the current research the maximum deflection of circular plates made of AA5010 and AA1100 alloys under blast load was investigated. Shock waves were produced by exploding a spherical charge in different distances from the center of plates. The ABAQUS software uses conwep equation for blast loading analysis. It was found the results of these simulations have about 30% to 40% inaccuracy in comp...

The Blast Wave Accelerator - Feasibility Study

This paper describes a new concept for propelling a projectile to hypervelocities and demonstrates the feasibility by numerical simulations. The concept employs imploding blast waves to accelerate a projectile which travels down a launch tube. The launch tube can be open to the atmosphere or sealed and maintained at some low pressure to minimize drag. The launch tube has a liner that contains a...

Energy-Dependent Gamma-Ray Burst Peak Durations and Blast-Wave Deceleration

Temporal analyses of the prompt gamma-ray and X-ray light curves of gamma-ray bursts reveal a tendency for the burst pulse time scales to increase with decreasing energy. For an ensemble of BATSE bursts, Fenimore et al. (1995) show that the energy dependence of burst peak durations can be represented by ∆t ∝ E−γ with γ ≃ 0.4– 0.45. This power-law dependence has led to the suggestion that this e...
