Computer simulation of the space charge dominated beam dynamics for external injection into the JINR Phasotron
A project of increasing the beam intensity of the 660 MeV JINR proton Phasotron up to 50 µA by an external injection of the H − beam with energy of 5 MeV is now under design. Computer simulation of the space charge dominated beam dynamics in Phasotron is reported. As follows from the simulation, the capture efficiency does not change too much when the beam space charge is taken into account.
EXTERNAL INJECTION INTO JINR PHASOTRON - COMPUTER SIMULATION II
Computer simulation of the beam dynamics is reported for the external injection (Fig. 1) into the Phasotron [1] of the preliminary bunched 5 MeV beam. The capture efficiency is found to be 45% and not too much dependent on the scattering by the foil.
Developmental aphasia: The perception of brief vowels and extended stop consonants
Abstract Developmental dysphasics and matched controls were examined for their ability to discriminate (a) two synthesized vowel-vowel syllables and (b) two synthesized consonant- vowel syllables. For both vowels and consonants, dysphasics were impaired when the discriminable components of the two stimuli were brief (43 msec) but unimpaired when these components were 95 msec or longer. It is concluded that developmental dysphasics have no difficulty in discriminating transitional auditory information as such and that their impaired discrimination of synthesized stop consonants is attributable solely to the brief duration of the discriminable components.
