This paper presents the implementation of a malware trap device. We created a virtual usb device through the use of microvisor on the ARM platform.

A penning trap for studying cluster ions

2008

We propose to use a Penning trap for spectroscopy of stored cluster ions. A similar device has been built for the purpose of mass measurements of short-lived nuclei produced at the on-line isotope separator ISOLDE/CERN. A resolving power of 500,000 in a mass measurement of39K and an accuracy of 2 × 10−7 for the85Rb/39K mass ratio were obtained. An efficiency for in-flight capture as high as 70% was achieved. The method provides very high sensitivity since typically only 10 to 100 ions are stored in the trap. We intend to perform laser spectroscopy on trapped Na clusters as a first application of the trap technique.

Experimental studies at JYFLTRAP

2007

JYFLTRAP is a Penning trap system at the accelerator laboratory in Jyvaskyla, Finland that enables high-precision experiments with stored, exotic species that are produced at the IGISOL facility. On one hand, these can be performed within the trap itself, like e.g. mass spectrometry. On the other hand, the trap can be used to provide the highly purified species for further experiments, e.g. for trap-assisted nuclear decay spectroscopy. This contribution focuses on these two possible applications with the presentation of some recent results on superallowed beta decays.

Status of the SHIPTRAP Project: A Capture and Storage Facility for Heavy Radionuclides from SHIP

2001

The ion trap facility SHIPTRAP is being set up to deliver very clean and cool beams of singly-charged recoil ions produced at the SHIP velocity filter at GSI Darmstadt. SHIPTRAP consists of a gas cell for stopping and thermalizing high-energy recoil ions from SHIP, an rf ion guide for extraction of the ions from the gas cell, a linear rf trap for accumulation and bunching of the ions, and a Penning trap for isobaric purification. The progress in testing the rf ion guide is reported. A transmission of about 93(5)% was achieved.

Temporary Employment in the Nordic Countries: A `Trap' or a `Bridge'?

The Stockholm–Mainz ion trap project

1993

A new ion trap facility is described which is dedicated to studies of highly charged ions in a Penning trap. Such a trap will be connected to sources of highly charged ions, in particular the electron beam ion source CRYSIS, at the Manne Siegbahn Institute for Physics. The use of highly charged ions in a Penning trap increases the cyclotron frequency with a factor proportional to the charge which leads to a higher resolution. Also, the possibility to vary the charge state makes it possible to search for and identify different systematic effects. Thus, a substantial increase in accuracy can be expected. In addition, the combination of high charge state ions and a Penning trap allows new appl…

First mass measurement at JYFLTRAP

2004

The first mass measurements at JYFLTRAP facility are reviewed. Those are also first ever direct mass measurements of the heaviest Zr-isotopes. Results are compared to atomic mass evaluation data and the recent calculations. The first TOF-resonances from high-precision trap and an implication to high-precision mass measurements are discussed.

Fractional frequency collective parametric resonances of an ion cloud in a Paul trap

Cupole e campanili: forme e significato

2012

Cupole e campanili costituiscono elementi fortemente caratterizzanti i nostri panorami urbani, rappresentando spesso la testimonianza tangibile del potere degli ordini religiosi che, attraverso questi elementi di forte impatto visivo, affermano la propria presenza in un determinato contesto. Il contributo mira a offrire una sintesi sul tema delle cupole e dei campanili con riferimento in particolare all'area del trapanese, ricca di testimonianze significative.
