Description
Technical field
The invention belongs to transmissive window fields, and in particular to based on sapphire pulse HIGH-POWERED MICROWAVES transmissive window.
Background technology
LHW current drive (LHCD) is a kind of important non-faradic that tokamak maintains long pulse steady-state operation
Flow driving means.The microwave power of wave source output is coupled to plasma by waveguide transmission line finally by lower hybrid wave launching antenna
In.Due to being in high vacuum state inside tokamak, it usually needs it is saturating that microwave is installed between transmission line and lower hybrid wave launching antenna
Window is penetrated, plays the purpose of isolated vacuum and high power transmission.The 3.7GHzLHCD systems of HL-2A devices, high-transmission, low-loss
Microwave transmission window be essential.Requirement of the lower hybrid wave heating system to microwave transmission window：Low reflection, high transmittance.
Vacuum insulation can bear 250kW/2s microwave powers.Effective water cooling.Has window sparking monitoring capability.Current most of microwaves
Window all using niberlox as wave transparent medium, but due to its high toxicity to processing, test and maintenance all bring compared with
Burden.For the lower hybrid wave system of HL-2A devices, since its single-shot run time is shorter, the thermal stress caused by window
Also it is corresponding to reduce, therefore sapphire application also becomes possible.
Invention content
The object of the present invention is to provide a kind of sapphire microwave transmission windows of suitable LHCD transmission line systems.Main solution
The problem of certainly window temperature rises.It is the reliable selection of window material since sapphire material heat conductivility is preferable and nontoxic.
Technical scheme is as follows：One kind is based on sapphire pulse HIGH-POWERED MICROWAVES transmissive window, including water jacket,
Outside installation water inlet and water outlet, have inside it sapphire with can valve material, can be and blue precious inside valve material welding water jacket
The edge of stone is welded on can be on valve material；Right side round flange and left side round flange are installed in the rear and front end of water jacket respectively, and left side
Round flange installation left side rectangular flange, right side round flange right side installation right rectangular flange.
The water jacket is circular ring type structure.
There is Arc detection mouth on the rectangular flange of left side.
The water jacket is stainless steel material.
It is described can valve material and sapphire there is similar coefficient of thermal expansion.
The remarkable result of the present invention is：After metallizing edges, sapphire window is with having close coefficient of thermal expansion
Can valve material carry out vacuum welding, achieve the purpose that the hermetic seal of window both sides.
Rationally design window and forms size using impedance match method and optimization software, effectively reduce reflectance factor with
And window loss.Sapphire window is cooled down using edge water-cooling structure, preventing energy from excessively depositing causes window damaged.
Rectangular waveguide narrow side is open to monitor window sparking situation.

Specific embodiment
Based on sapphire pulse HIGH-POWERED MICROWAVES transmissive window, including water jacket 3, water jacket 3 is circular ring type structure, external to pacify
Be packed into the mouth of a river 4 and water outlet 5, have inside it sapphire 1 with can valve material 2, can valve material 2 weld inside water jacket 3, it is and blue precious
The edge of stone 1 is welded on can be on valve material 2；Right side round flange 6 and left side round flange 9 are installed in the rear and front end of water jacket 3 respectively, and
The installation of left side round flange 9 left side rectangular flange 7,6 right side installation right rectangular flange 10 of right side round flange, in left side rectangular flange
There is Arc detection mouth 8 on 7.
Water jacket 3 is stainless steel material.
The present invention is based on sapphire pulse HIGH-POWERED MICROWAVES transmissive window, and the pulse power born reaches 250kW, pulse
Width reaches 2s, and pulse energy reaches 500kJ, and sapphire material lossy microwave angle tangent is smaller, the energy being deposited in sapphire
Amount can be taken away by edge cooling water quickly.
