Abstract

In order to further improve the condition of road tunnel traffic engineering facilities, and thus improve the safety of tunnel operations. The paper analyzes the inspection results of traffic engineering facilities in dozens of tunnels in China, and summarizes the common operational safety risks of traffic engineering facilities. Then puts forward corresponding risk prevention and control measures, which is helpful to improve the status of tunnel traffic engineering facilities. It has certain guiding significance for the safety management of road tunnel operation.

Abstract

The hydraulic model is an important experiment system for studying the hydrological characteristic of river, lake and choosing the engineering project of port, dam and sea-route. The quality of the hydraulic model tests mainly lies on the measurement and control technology. This paper presents a hydraulic model tests control system which employing industrial computer and PLC as main controller, tracking water level as measuring meter. The flux and water level double loop control architecture is employed. The fuzzy self-adaptive PID algorithm is employed to control water level and flux. This control system has been applied in practice hydraulic model tests.

Abstract

The Muon Ionization Cooling Experiment (MICE) will demonstrate ionization cooling in a short section of a realistic cooling channel using a muon beam at Rutherford Appleton Laboratory in the UK. The coupling magnet is a superconducting solenoid mounted around four 201 MHz RF cavities, which produces magnetic field up to 2.6 T on the magnet centerline to keep muons within the iris of RF cavities windows. The coupling coil with inner radius of 750 mm, length of 285 mm and thickness of 102.5 mm will be cooled by a pair of 1.5 W at 4.2 K small coolers. This paper will introduce the updated engineering design of the coupling magnet made by ICST in China. The detailed analyses on magnetic fields, stresses induced during the processes of winding, cool down and charging, and cold mass support assembly are presented as well. [ABSTRACT FROM AUTHOR]
