A Super-Conducting Linac Driver for the HFBR
This paper reports on the feasibility study of a proton Super-Conducting
Linac (SCL) as a driver gor the High-Flux Breader Reactor (HFBR) at Brookhaven
National Laboratory (BNL). The Linac operates in Continuos Wave (CW) mode to
produce an average 10 MW of beam power. The Linac energy is 1.0 GeV. The
average proton beam intensity is 10 mA.Comment: 3 page

Impedances And Instabilities Of The Ags Booster
In this paper we review calculations done recently to demonstrate the stability of beam bunches in the AGS Booster for both cases of protons and heavy ions. 1 ref., 2 figs., 2 tabs
A Super-Conducting Linac Injector for the BNL-Ags
This paper reports on the feasibility study of a proton Super-Conducting Linac (SCL) as a new injector to the Alternating Gradient Synchrotron (AGS) of the Brookhaven National Laboratory (BNL). The Linac beam energy is in the range of 1.5 to 2.4 GeV. The Beam intensity is adjusted to provide an average beam power of 4 MW at the top energy of 24 GeV. The repetition rate of the SCL-AGS facility is 5 beam pulses per second
Light-cone fluctuations and the renormalized stress tensor of a massless scalar field
We investigate the effects of light-cone fluctuations over the renormalized
vacuum expectation value of the stress-energy tensor of a real massless
minimally coupled scalar field defined in a ()-dimensional flat space-time
with topology . For modeling the influence of
light-cone fluctuations over the quantum field, we consider a random
Klein-Gordon equation. We study the case of centered Gaussian processes. After
taking into account all the realizations of the random processes, we present
the correction caused by random fluctuations. The averaged renormalized vacuum
expectation value of the stress-energy associated with the scalar field is
presented
Media devices in pre-school children: the recommendations of the Italian pediatric society
BACKGROUND: Young children are too often exposed to mobile devices (MD) and most of them had their own device. The adverse effects of a early and prolonged exposure to digital technology on pre-school children has been described by several studies. Aim of the study is to analyze the consequences of MD exposure in pre-school children. METHODS: We analyzed the documented effects of media exposure on children's mental and physical health. RESULTS: According to recent studies, MD may interfere with learning, children development, well being, sleep, sight, listening, caregiver-child relationship. DISCUSSION: Pediatricians should be aware of both the beneficial and side effects of MD and give advice to the families, according to children's age. CONCLUSION: In according to literature, the Italian Pediatric Society suggest that the media device exposure in childhood should be modulated by supervisors
