关于我

我不可能做到别人要求我做每一件事,我只有足够时间去做我该去做的事情。如果我无法把每件事情都作到尽善尽美,这便意味着我想做的事情已经超过了我该去做。认清了自己的人生坐标,我的生活变得更为简单了,作息安排也更为合理。 魅力由它而生,它是苦难的根源,也是塑造坚强现在的原因。愿意相信别人,能够承担别人的信任,相信别人却是极其艰难的决定。心底的秘密存在于过去,找到那个能接受过去的人,就能有勇气焚毁所有的担心,融化冰封的城堡,让世界大地回春。

探秘俄罗斯的强子对撞机,多图

Today we’ll have a look at a hadron collider of the Nuclear Physics Institute in Novosibirsk. Russian scientists from the Institute of Nuclear Physics, located in the city of Novosibirsk, are trying hard to enhance LHC’s performance 100 times.

今天让我们来看一看位于俄罗斯新西伯利亚市核物理研究所的强子对撞机。该研究所的俄罗斯科学家们正努力将其性能提高100倍。



Total number of the Institute’s employees accounts for 2900 people.

该研究所共有2900名成员。

The entire process started with antiparallel E-beams (AEB-1). The first collider in the world was built in 1963 to examine the possibilities of the beams in experiments on physics of elementary particles. AEB-1 was the first collider where beams circulated and collided with one another in the vertical plane.

该研究所起步于这台反平行排列电子束暴光机(AEB-1)。世界上第一台对撞机于1963年诞生,其目的是为了检验试验中电子束对基本粒子的物理特性所产生的影响。而AEB-1是第一台实现电子束循环并使之在垂直面上互相碰撞的设备。

Today the Institute can boast of having two accelerators, AEBB-4 and AEBB-2000. Development of AEBB-2000 made it possible to create the greater hadron collider.

如今,该研究所拥有两台引以为豪的加速器:AEBB-4和AEBB-2000。其中AEBB-2000使更高性能强子对撞机的诞生成为可能。

Momentary foot cooling with the help of nitrogen.

通过氮气进行降温的瞬间。

The new collider has to provide exact measurements of electron-positron annihilation. Positron and electron (particle and anti-particle) can annihilate in collision turning into electromagnetic radiation. In some cases other particles that consist of two or three quarks can be obtained in the result of the collision. Internal composition of protons and neutrons is not examined completely.

新型的对撞机必须提供电子-正电子湮灭的准确测量结果。正电子和电子(粒子和反粒子)在对撞中会发生湮灭,并产生电磁辐射。在某些情况下,一些拥有2个或3个夸克的粒子将可能在对撞后被获取。但科学家尚未对质子和中子的内部构成形成完整的认识。

Control unit of AEBB-2000.

AEBB-2000的控制单元。

You are in a control room. Where is your radiation hazard meter?

提醒:你目前所在的地点是控制室。你的辐射监测仪在哪里?

Are you moving to the AEBB-2000 or to the basement? Do you have a radiation hazard meter with you?

提醒:你是要去AEBB-2000还是去地下室?你是否携带了辐射监测仪?

The AEBB-2000 accelerator is a unique facility for carrying out experiments with anti-parallel electron-positron beams of high energies.

 AEBB-2000加速器是一部独一无二的设备,它能实现高能量的反平行电子-正电子束试验。

The AEBB-4M can measure energy of particles by method of resonance depolarization with relative mistake up to 10-7 which is not available at any other laboratory in the world.

AEBB-4M 能够通过共振脱极化的方法测量粒子的能量,其相对误差目前为世界最小。

Nowadays most experiments aim at precision measurement of elementary particles mass.

当今多数的试验都以精确测量基本粒子的质量为目标。

The AEBB-4M complex is also used in experiments with beams of synchrotron radiation. Main directions are represented by archeology, biology, medicine, nanotechnology,etc.

AEBB-4M 综合设施也被用于电子束同步加速辐射试验。其主要应用方向包括考古学、生物学、医药、纳米技术等等。

The complex is used by over 30 Russian and foreign organizations.

设备的使用者是30多个俄罗斯及外国的组织。

The AEBB-4M complex occupies 366 meters.

AEBB-4M拥有366个仪表。

Here the experiments on nuclear physics are held when a stream of gas is injected into the vacuum chamber of the accumulator.

核物理试验在这里进行,试验时储能器的真空仓中将被注入一股气体。

The accumulator is 74,4 meters long.

该储能器的长度为74.4米。

The gasodynamic trap helps to examine important physical problems related to retention of thermonuclear plasma in long open magnetic systems.

气体动态捕捉器有助于检测与热核等离子体在大场强、开放式磁场中滞留相关的重要物理问题。

The trap is undergoing modernization. Thus, they will be using powerful injectors of new generation to heat plasma.

工作人员正在对气体动态捕捉器进行现代化改造。在改造完成之后,将可以使用强大的新一代注射器来加热等离子体。

Plasma trap GOL-3 holds experiments on studying interaction of plasma with the surface. It will help to choose optimal construction materials for elements of the thermonuclear reactor that contacts with hot plasma.

在GOL-3等离子体捕捉器中进行的试验是研究等离子体与物体表面的相互作用。这将有助于研究人员挑选出最适合热核反应堆的建筑材料,因为热核反应堆与高温等离子体会发生接触。

Free electron laser works as follows: an electron beam goes through the section with alternating magnetic field making electrons move along a wavy path and not a straight one. Relativistic electrons produce light that goes to the optical resonator with absolute vacuum inside.

自由电子射线是这样工作的:一束电子穿过具有交变磁场的部分,在磁场作用下电子束的运动轨迹将呈波浪状而非直线。相对论电子所产生的光线将进入完全真空的光学谐振器当中。

Two massive copper mirrors are located on the opposite parts of the tube. While moving from one part of the tube to the other one, the light becomes more and more powerful. A part of the force goes to the consumer. Electrons that were deprived of their energy in favour of electromagnetic radiation go back to the resonators and get inhibited there.

在管道的另外一端安装了两面巨大的铜镜。在从管道一端移动到另一端的过程中,光会越变越强。其中的一部分能量将进入消耗装置当中。而被剥夺了电磁辐射能量的电子将回到谐振器中并被抑制在那里。

Radiation is taken upward through the tubes filled with dry nitrogen.

管道中被注入了干燥的氮气,辐射将沿着管道由下至上地被提取。

Do you see how wide the walls are? Rules of radiation protection were followed to the maximum.

看见那些墙壁有多厚了吧?这里的辐射保护执行的是最高标准。
