The negative electrode in the X-ray tube, also known as the cathode, is responsible for producing a stream of electrons that are accelerated towards the positive electrode (anode). This electron stream generates X-rays when it strikes the anode, which are used for medical imaging and other applications.

What role does the negative electrode play in the operation of an x-ray tube?
The negative electrode, also known as the cathode, in an x-ray tube is responsible for producing a stream of electrons that are accelerated towards the positive electrode, or anode. These electrons collide with the anode, generating x-rays through a process called bremsstrahlung radiation. In summary, the negative electrode plays a crucial role in initiating the production of x-rays in an x-ray tube.

The radiation emitted from the xray tube and strikes the patient directly is called?
primary radiation
What is the difference between ccfl and eefl?
CCFL (cold cathode fluorescent lamp) is different from EEFL (external electrode fluorescent lamp) in that the glass tube of the CCFL contains a small wire electrode that conducts the voltage to excite the gasses in the tube. The glass tube is molded around the electrode and that junction creates a possible point for the gasses to escape and the lamp to fail. EEFL is a completely sealed glass tube with a metal cap or conductive paint on the end acting as the electrode. When the proper voltage is applied to the external electrode, a capacitive connection is established between the electrode and the gasses within the tube and the lamp illuminates. Because the electrodes in CCFL's are in direct contact with the rare gasses, CCFL's run warmer than the EEFL's which are completely cool.
Which factor controls the amount of radiation emitted from the xray tube?
The exposure factors control the amount of radiation emitted from the x-ray tube. These factors include tube current (mA), tube voltage (kVp), and exposure time (seconds). Adjusting these parameters can alter the amount of radiation produced in the x-ray tube.

What is the positive electrode of an electron tube?
anode
How could a sample gas be collected at the positive electrode when using electrolysis for copper?
To collect a sample gas at the positive electrode during electrolysis for copper, a gas collection tube can be placed directly above the positive electrode. As the electrolysis is carried out, the gas generated at the positive electrode will rise and move into the collection tube, allowing for easy sampling and analysis.
Reasons for no air in vacuum tubes?
Vacuum tubes perform their various functions on the principle of streaming electrons: that is electrons able to fly across space from one electrode to another. If there is air in the tube then this is a barrier to the electron's flight and the tube cannot function.
Grid control X-ray tube versus dual X-ray tube?
A Grid Controlled X-ray Tube is a triode in which a third electrode is introduced between the Anode and Cathode. This electrode is normally neutral so the x-ray production can take place. However, one can decide when to cut the exposure by introducing negative charge on this. This will then stop (repel) the electron from reaching the Anode and x-ray production is stopped. Therefore, the elecrode with a negative charge can as a timer or if chrge is given intermittently, it acts as a device to have flouroscopy in pulses.
How does negative pressure work in a chest tube?
Negative pressure in a chest tube creates suction that helps remove air or fluids from the pleural space. This allows the lung to re-expand and prevents conditions like pneumothorax or pleural effusion from developing. The negative pressure helps the chest tube drain effectively and promotes proper lung function.
What is the maximum amount of leakage radiation that can escape from an xray tube?
1 mGya/hr at 1 meter.
What are the people that do x rays?
They are radiologic technologists, or radiographers for short.
